"You Ain't Seen Nothing Yet" is a song by Canadian rock band Bachman–Turner Overdrive (BTO). The song was written by Randy Bachman for the band's third studio album Not Fragile (1974). It was released as a single in 1974, with an instrumental track "Free Wheelin'" as the B-side. It reached the number one position on the Billboard Hot 100 singles chart and the Canadian RPM chart the week of November 9, 1974, as well as earning the band their only major hit single in the United Kingdom, peaking at number 2 on the UK Singles Chart. The follow-up single, "Roll on Down the Highway", was also a minor UK hit. Theme The lyrics for the song tell of the narrator meeting a "devil woman" who gives him love. The chorus of the song includes the song's famous stutter, and speaks of her looking at him with big brown eyes and saying, "You ain't seen nothin' yet. B-b-b-baby, you just ain't seen na-na-nothin' yet. Here's somethin' that you're never gonna forget. B-b-b-baby, you just ain't seen na-na-nothin' yet." Development "You Ain't Seen Nothing Yet" was written by Randy Bachman. In The Rolling Stone Record Guide, writer Dave Marsh called the song "a direct steal from The Who", but "an imaginative one". The chords of the chorus riff are very similar to the ones used by the Who in their song "Baba O'Riley", and also the stuttering vocal is reminiscent of "My Generation". Bachman insists that the song was performed as a joke for his brother, Gary, who had a stutter, with no intention of sounding like "My Generation". They only intended to record it once with the stutter and send the only recording to Gary. Bachman developed the song while recording BTO's third album, Not Fragile (1974). It began as an instrumental piece inspired by the rhythm guitar on Dave Mason's "Only You Know and I Know". Bachman says "it was basically just an instrumental and I was fooling around... I wrote the lyrics, out of the blue, and stuttered them through." The band typically used the song as a "work track" in the studio to get the amplifiers and microphones set properly. But when winding up production for the album, Charlie Fach of Mercury Records said the eight tracks they had lacked the "magic" that would make a hit single. Some band members asked Bachman, "what about the work track?"
