The band Vanilla Fudge took the former #1 Supremes' song "You Keep Me Hanging On' and re-did it as a psychedelic, hard rock tune. Released in 1967, this cover version surprised everyone by climbing to #6 on the Hot 100. The edited 45 was under three minutes long, which led to a lot of album sales for the band because fans found out the album version was almost seven minutes long. A great song, it heavily influenced my love for hard rock.
