The story behind “Ain’t Seen Nothin’ Yet” is like that told about many classic rock songs. The band jams in the studio, makes up some dummy lyrics and poof a hit is created.
“Ain’t Seen Nothin’ Yet” appeared on the 1974 album “Not Fragile”. It was written as a jam in A to test sound levels. They recorded it with lyrics that didn’t mean anything, mistakes and all. Randy Bachman’s vocal used stuttering, influenced by his brother Gary’s stuttering. When the record company didn’t hear a hit in the other eight songs recorded for the album, the engineer suggested the jam song. They loved it, warts and all, and didn’t want them to re-record it.
Fred Turner is the Turner in Bachman Turner Overdrive.
He was recommended to Randy Bachman by fellow Canadian, Neil Young. Fred could not only play bass, but could sing like a Harley Davidson. He did the lead vocals on two of BTO's biggest hits; "Roll On Down the Highway" and "Let it Ride".
On this song, Fred incorporates some of his formal music training into his bassline. On the verses, he outlines the chord tones instead of just pumping on the root note. My favorite part is in the pre-chorus where he moves down chromatically to the next chord (listen on the part with the lyric "and she looked at me with those big brown eyes and said.."That is a common jazz bass technique to approach notes from above, but it sounds great in rock songs as well.
