Bachman-Turner Overdrive scored their first #1 single on Nov. 9, 1974, with “You Ain’t Seen Nothing Yet.” The song was a last minute addition to the band’s third album, Not Fragile, which had been released in August.
The song was recorded once, as a joke, according to Randy Bachman, the former Guess Who guitarist who formed BTO with his brother and C.F. Turner.
Bachman had been noodling with a guitar riff, which bears a strong but truncated similarity to the Who’s “Baba O’Riley.” The vocal also featured stuttering in its chorus, akin to the Who’s “My Generation.”
Bachman insisted the demo recording was nothing more than a private joke for his brother Gary, who had a speech impediment. He said the song ended up on the album at the insistence of Mercury Record’s Charlie Fach, who had signed the band in 1973 and was looking for a hit single.
Bachman argued against releasing it as a single, but eventually agreed after the LP’s initial single, “Roll On Down The Highway,” failed to crack the Top 10.
