 Then, there's a complex middle section with vocals (performed by Tina Turner & The Ikettes, uncredited) backed by percussion, singing some of the verses.Zappa follows singing the last verses and finally there's the coda, where the line from the chorus ("Moving to Montana soon...," sung by Tina Turner and the Ikettes) is repeated constantly and answered by a high-pitched "Yippy-Aye-O-Ty-Ay" (sung by Kin Vassy).This goes on until it fades out towards the six-and-a-half minute mark.
