On This Day in 1974, Bachman-Turner Overdrive Hit No. 1 With a Song That Started as a Joke Between Brothers and Became a Worldwide Smash

Bachman-Turner Overdrive’s “You Ain’t Seen Nothing Yet” reached No. 1 on the US Hot 100 on 9 November 1974. The band’s only American chart-topper began as an informal studio recording and became an international hit after a record executive persuaded them to release it.

The song was improvised while the band worked on its album *Not Fragile*, with Randy Bachman stuttering the title as a joke between brothers. The group initially planned to make just one copy for Gary Bachman and did not polish the track. After hearing it, Mercury Records executive Charlie Fach insisted it be included on the album as recorded.
