Rolling Stone contributing editor Rob Sheffield has been entertaining us for years with his sly, hysterical, and unique take on pop culture, from his merry meanderings through movies and television to music and more. The Brooklyn-based Sheffield has just released his third book, Turn Around Bright Eyes: The Rituals of Love & Karaoke (Harper, August 6, $25.99), the follow-up to 2007’s Love Is a Mix Tape: Life and Loss, One Song at a Time and 2011’s Talking to Girls About Duran Duran: One Young Man’s Quest for True Love and a Cooler Haircut. The new tome, which features such song-related chapter titles as “Total Eclipse of the Heart,” “Livin’ on a Prayer,” “99 Luftballons,” “Hot Legs,” “Debaser,” and “Stop Draggin’ My Heart Around,” reveals Sheffield and his wife’s addiction to karaoke, something we can’t say we share but makes for some very funny reading. There should be some very funny reading and discussion on August 23, when Sheffield presents the book at the Barnes & Noble at 2289 Broadway at 82nd St. at 7:00. “Once upon a time I was falling apart. Now I’m always falling in love,” the book begins. “This spiritual quest, like so many spiritual quests, involves Bonnie Tyler,” Sheffield adds. That’s more than enough for us; count us in.
