A bass that throbbed like a heartbeat, a piercing winding blues-rock riff and a snarling Van Morrison vocal made Them's cover of Big Joe Williams' country blues classic "Baby Please Don't Go" a big U.K. hit single. Although it has sometimes been reported or speculated that Jimmy Page was used as a session man to play lead guitar on the track, Them guitarist Billy Harrison has claimed it as his own work. "I played it for a year before it ever got on their record," he said. "What he basically did was, in chords, augment the bass playing."
