Also, in transcribing the lyrics (which I've decided to do to all of the songs I write about here, provided I'm commenting on the lyrics), I discovered that the first word of each line of the second verse starts with P:
Put your frock on, Jean-Marie(It might technically be the third verse, if "My name is Bill, and I'm a headcase..." is an-other verse, but I think that's a bridge. I might be wrong; I'm bad at structural terminology.)
Pluck your hair, Felicity
Paint your nails, little Sally-Joy
Put this wig on, little boy
I think the words that start with P are too far away for it to be alliteration (at least in a strict sense), but it still indicates how the boy is forced into conforming with the girls.
