The song is a
twelve-bar blues in the key of G in standard tuning. Bassist
Dusty Hill has said the song was written at a sound check in about ten minutes. The recording was produced by
Bill Ham and recorded and mixed by
Terry Manning.
Billy Gibbons said, "We were in Florence, Alabama, playing in a rodeo arena with a dirt floor. We decided to play a bit in the afternoon. I hit that opening lick, and Dave Blayney, our lighting director, gave us the hand [twirls a finger in the air]: 'Keep it going.' Then Dusty leaned over, and said, “What are we going to call this thing?". The Texas singer
Roy Head had a flip side in 1966, 'Tush Hog.' Down South, the word meant deluxe, plush. And a tush hog was very deluxe. We had the riff going, Dusty fell in with the vocal, and we wrote it in three minutes. We had the advantage of that
dual meaning of the word 'tush' [grins]. It's that secret blues language — saying it without saying it." ==Reception==
