"Rick Wright vocal?== 
 What part does Wright supposedly sing lead on? I know there's a source that says he sings lead on part of this song but I just don't hear it. Mason sings the rhyming couplets and Gilmour clearly sings lead on the rest. The only part I question is the ""Mrs. Clegg"" part, but that's a group vocal without a particular lead part (and Gilmour seems to be carrying the melody anyway).
