It's still popular outside Rugby Song circles too, Malcolm. One of those folk songs which can still be collected in pubs 'cos one of the locals has taken the trouble to know it and everyone else sings the chorus.

The one I posted here hasn't got a chorus, and I'm not actually sure it's from The Yetties. Their version, as also Adge Cutler's, seems to me to have had the usual chorus. I liked the directness of this one, without too much indelicacy.

Cheers!
