Peter Wolf has been thinking about writing a book “for a long time.” But making a new solo album is what really prompted the former J. Geils Band frontman to get serious about it.

Wolf is “about 80 percent” finished with the album, which will be his first since 2016’s A Cure For Loneliness. “It occurred to me that my solo recordings, a lot of them went unnoticed, and I realized that if I put this out with the way things are these days, it can turn to vapor quite easily and be another lost solo effort,” Wolf — who’s just published Waiting on the Moon: Artists, Poets, Drifters, Grifters, and Goddesses (Little, Brown) — tells Billboard. “So I thought, ‘Well, maybe now is the time to write that book I’ve been talking about for decades.’ I think if the book connects with people it would even put the wind beneath my wings to finish the record and put it out.”

Wolf also received a meaningful push from writer Peter Guralnick, best known for his acclaimed biographies of Elvis Presley, Sam Cooke and Sun Records founder Sam Phillips. “He read some of the things I was writing,” Wolf recalls, “and he said, ‘Y’know, Pete, you better finally do this book ’cause a lot of the people you’re gonna want to have read it might not be with us at the pace you’re going.’ That was a profound statement for me.”

While it tracks from Wolf’s childhood to the relatively present day, Waiting on the Moon is not a standard, linear memoir. Rather, it’s a collection of stories — and a fascinating, good-humored one at that — as the New York-born Wolf regales readers with his Forrest Gump-like life of encounters with the famous, starting with a chapter titled “I Slept With Marilyn Monroe,” in which Monroe literally fell asleep on a 10-year-old Wolf while both attended a screening of the Jules Dassin film He Who Must Die at a local movie theater. (Not to worry; Monroe was with then-husband Arthur Miller and Wolf’s parents were on his other side.)

From there it’s off to the races as Wolf recounts his interactions and relationships with blues heroes such as Muddy Waters, Howlin’ Wolf and John Lee Hooker (sometimes in his Boston apartment) as well as Bob Dylan, Van Morrison, the Rolling Stones, John Lennon and Harry Nilsson, Sly Stone, Aretha Franklin and more. He crosses paths with music biz luminaries such as Ahmet Ertegun, Bhaskar Menon, Jon Landau and Dee Anthony, gets on the wrong side of Alfred Hitchcock by declining an offer of an alcoholic drink and finds himself being courted for a part in Martin Scorsese’s The Last Temptation of Christ.

Eleanor Roosevelt, Louis Armstrong, Andy Warhol, onetime roommate David Lynch, Julia Child and Tennessee Williams are also among Wolf’s encounters in the pages.

“My goal was to make a book of short stories, treat each chapter like its own short story,” explains Wolf, who was an art student and radio DJ in Boston as well as a musician — first with the Hallucinations, then with the J. Geils Band starting in 1967. He fronted the latter to multi-platinum worldwide fame with Freeze-Frame in 1981, which topped the Billboard 200 in 1982 and produced the six-week Billboard Hot 100 No. 1 “Centerfold” that same year. After being asked to leave the group in 1983, Wolf kicked off a solo career with 1984’s Lights Out (its title track hit No. 12 on the Hot 100). “There was no timeline. I wasn’t concerned, in a way, about the beginning, middle and end; each story has its own beginning, middle and end. And I didn’t want this to be a kiss-and-tell book; I just wanted to write about these incredible people that I had the privilege to meet and to get to know to certain degrees and capture that.”

Wolf adds that “the two subjects I didn’t want to write about was my marriage to Faye Dunaway and the J. Geils Band,” but both are there — particularly the former, whom Wolf has been loath to discuss in this kind of detail during and after their marriage from 1974-79. “Faye was this very determined, talented person and we loved each other,” Wolf says. “I was just trying to bring her, and our relationship, somewhat to life and all the adventures we shared in it. I didn’t talk about it (before) because I would talk about my music, talk about the records, and all the other stuff was kind of private. But I was writing about the adventures in my life, and certainly she and I shared many of them. I was very surprised how quickly the stories came out.

“Of course there’s regrets; one has regrets and wishes they could do things differently, and I think I’ve expressed that in all the chapters. Some were silly, stupidities that I’ve made, and I don’t try to disguise those. It all flowed through naturally once I got into the crux of it.”

‘Waiting on the Moon’

The J. Geils Band, meanwhile, is treated as a through-line in the book until a later chapter in which Wolf writes about explicitly about how it came apart at the peak of its career.

“It was a great shock to me, and it was a sea change for me,” says Wolf, who was part of Geils reunion tours from 1999-2015. The book also includes a vivid retelling of him being beaten up in a London pub while on his way to the band’s performance at the 1989 Pinkpop Festival in the Netherlands. “I tried to write honestly about it, my experience of it all and how I felt. I was committed to the band; it was my life, and even with my marriage to Faye our careers always came first. In other chapters you can see how hard I tried working to keep the band relevant and moving ahead, so of course when things did fall apart it was a very painful thing for me. What I didn’t add in the book that I was asked to leave the band in 1968 because they felt my vocal abilities were holding back the band.”

Wolf has recorded an audio version of Waiting On the Moon and has a handful of author appearances planned this month, starting Tuesday (March 11) at the Harvard Bookstore in Cambridge, Mass., and including stops in New York, New Jersey, New Hampshire, Philadelphia and Connecticut. He did, however, cancel a planned March 21 stop at the Kennedy Center in Washington D.C. “due to the egregious firing of staff by the new administration.”

Wolf is also planning to get to work on the album, working with “the same cast of characters” who helped with his last few albums. “I think it’s got some really memorable songs, and I took a long time in putting it together,” he says, adding that he foresees a return to performing as well. “Yeah, that’s what I do. But the book really required a sabbatical. It’s like making a really good record that you’ve got to hunker down and commit to.” A reissue of the J. Geils Band’s 1972 concert album “Live” Full House is also slated for this year, according to Wolf.

Also on the future docket may be an induction in the Rock & Roll Hall of Fame, which has eluded the J. Geils Band over the course of five nominations between 2005-2018. Wolf has inducted Jackie Wilson and the Paul Butterfield Blues Band at previous ceremonies, and while he notes that “it’s a situation I have no control over” he makes it clear that it’s something he’d like to see happen, eventually.

“Yes, it would be a nice honor,” Wolf says. “I do feel the Geils Band contributed a lot in the AOR period of rock n’ roll. Not unlike the Stones we introduced a lot of people to (artists) like the Contours and Otis Rush and Muddy Waters and doo-wop… yet the Geils band has been looked over. I think we worked very hard for 17 and a half years, and I think we made some kind of contribution. But, to quote a Johnny Mathis song, ‘it’s not for me to say.’”
