Vanilla Fudge's 1967 psychedelic/hard rock remake of "You Keep Me Hangin' On" reached #6 on the Hot 100 chart two years after the release of the Supremes' recording. While the version released on 45 RPM single was under three minutes long, the album version was extended to six minutes and forty-five seconds. The recording, done in one take, was Vanilla Fudge's first single.
The under three minute version is what most people heard on the radio. Not too many people in my peer group were buying albums back then unless it was The Beatles or a band of similar stature.
Like I said I am one of those who actually remember the 60's
