In his memoir, “From Hobo Flats to The 5th Dimension,” founder of The 5th Dimension and life-long friend, LaMonte McLemore earmarks Billy Davis, Jr.’s interpretation of Sam Cooke’s “A Change Is Gonna Come” as incomparable, bringing a tear to his eye. As biographer of both The original 5th and “Mac,” I was so proud to have it released (in medley with “People Gotta Be Free”) as a rarity selection on the current CD chart-topper, “Playlist: The Very Best of The 5th Dimension” on Sony-Legacy. Florence LaRue confided to a recent audience at her solo cabaret show, “My all-time favorite song by The 5th Dimension is ‘Misty Roses!’” That’s Billy’s “sweet-soul” side, way back-in-the-day from the very first “Up-Up and Away” album. Compare this to his “flip side,” as both the bluesy “When Something is Wrong with My Baby” and the gritty “Steppin’ In” stop the show “live in person,” and on the exemplary Marilyn McCoo & Billy Davis Jr.’s latest double volume Live CD!
