From Woodstock to “The Banana Splits,” from “Sgt. Pepper” to “H.R. Pufnstuf,” from Altamont to “The Partridge Family,” Groovy is a far-out trip to the era of lava lamps and love beads. Profusely illustrated, in psychedelic color, Groovy features interviews with icons of grooviness such as Peter Max, Brian Wilson, Peter Fonda, Melanie, David Cassidy, members of the Jefferson Airplane, Cream, the Doors, the Cowsills and Vanilla Fudge; and cast members of groovy TV shows like “The Monkees,” “Laugh-In” and “The Brady Bunch.”
