The lyrics refer to several incidences, as usual, that the Stones have experienced, a mishmash of sorts.
Gaz, guess "what" the "moon is yellow/I'm like jello" Staring down your tits" mean?
moon is yellow = "a sign," perhaps?
LIS, yellow? ("Oh no, not you again")ahahahahhahahah!
jello = Both Mick and especially Keith, love tits
makes them weak to see them
Ronnie too, goes ape over tits at concerts.
Staring down your tits, = at a concert = staring from the stage
"Fuc the Rock babe, I want the Roll." (KR)
