To get back to worst songs: I think I should mention one with the singular distinction of having been banned from the Anchor Middle Bar at Sidmouth. No, not Wild Rover, that was just penalised with a big fine. I refer to the Traffic Light Song.

First verse:
I like traffic lights,
I like traffic lights,
I like traffic lights,
That is what I said,
I like traffic lights,
I like traffic lights,
I like traffic lights,
Except when they are red.

Chorus:
He likes traffic lights,
etc.

The tune, such as it is, is the height of banality, if that isn't a contradiction in terms.
I don't know how many verses there are, the singer never got beyond the fourth.
