Here's a summary (via amazon.com)
A groupie is to a rock band as Mary Magdalene was to Jesus, asserts L.A. rock author Des Barres (I'm with the Band) in this eager, self-congratulatory attempt to rehabilitate the term groupie through two dozen fun and well-documented examples of rock muses since the 1960s. Des Barres steers her interviewees to underscore their important role in making their rock star boyfriends look good and play well, such as Tura Satana, given the dubious title Miss Japan Beautiful, who met awkward young Elvis Presley on the burlesque circuit in the mid-'50s and taught him his shimmying moves.
Des Barres recalls her groupie rivals back in the day, including Patti D'Arbanville, Bebe Buell, Lori Lightning and Catherine James. Cynthia Plaster Caster, the Rodin of Rock, shares her descriptions of her plaster replicas of rock stars' penises (including that of Jimmy Hendrix), while Dee Dee Keel spills tales of her oral exploits for British rockers with deplorable bathing habits, and male groupie Pleather relays Courtney Love's shaky self-esteem. In the end, it's all about the music, or as Pleasant Gehman sums it up blithely in this breathlessly gossipy scrapbook: Being a groupie is like worshipping at the church of rock and roll—and you are the high priestess.
The French version I translated was published by a French publishing house called Scali, which went bankrupt a few months after the book was published. So the book is almost impossible to find now in French (you can try second-hand bookstores and online sites perhaps). The English version is still available though.
