For my acting society it has been a tradition for many years, I am told, to sing this song before any performance as a sort of meditation/enthusiasm-building exercise. Here are the lyrics we use:

Rose, rose, rose, red
Shall I ever see thee wed?
I marry that thou shalt
When thou art dead.

I've spent ages pondering the possible meanings of this set of lyrics but there are quite a few possible ones (especially if you exchange the word "I" for "Aye") It seems that this more rhyming version is, then, more common in acting groups as mentioned by "Pied Piper" above.
