I have some words set to this lovely round that I got from some Thesps who used it in workshops as a warm up exercise.

Rose Rose Rose Rose
Shall I ever see thee red?
I brother that thou shalt
When I am dead

This rhymes and scans better than the above but I can't vouch for its origin.
I was told that it referred to the Wars of the roses but the language and the tune have a more Elizabethan flavour to my mind.

All the best PP
