On "Hand It Over" by Chuck Jackson, he's heard to say "I need a crap"!
In the first verse of "On The Stage of Love" by Ronnie & Joyce, mention is given to Bruce Forsyth.
There's also a track called "Get Off My Back" (not Marvin Sims), by a male/female duet whose name escapes me, and I swear the lyrics are "Get off of my back, and leave my penis alone"!
Eddie Holland - "If It's Love It's Alright" hears him say "I've got a funny feeling from my head down, tomatoes"
