Garage Rock
The song was written by Allen A. Jones and Willie David and first recorded by The Avantis in 1963. However, the cover of it by The Gentrys in 1965 went to #4 on the Billboard Hot 100 and #5 on Cashbox. The Bay City Rollers also covered the song in 1971. The song is actually one short recording, a false fade, and a repeat of the first part. This was done to have it conform with the timing of songs for AM radio.
The Gentrys were a rock band that formed in Memphis, Tennessee, in 1963. They started by playing for local dances an high school functions. “Keep on Dancing” was a million-seller and allowed them to appear on Hullabaloo, Shindig! , and tour with groups, including The Beach Boys and Sonny and Cher. There have been changes in lineup over the years, but the original group was Bruce Bowles (vocals), Bobby Fisher (saxophone, keyboards), Jimmy Hart (vocals), Jimmy Johnson (trumpet), Pat Neal (bass guitar), Larry Raspberry (guitar, vocals) and drummer Larry Wall (replaced by Rob Straube), and Larry Butler (keyboards). The lead vocals on “Keep on Dancing” were by Raspberry.
