We've had a number of threads on this song (see crosslinks above), but no solid information about where the song comes from. Is it from the Wurzels, or where's it from?
Joan from Wigan posted an ABC of the tune for her song in this thread (I'll post a MIDI when MIDI FTP gets fixed) - is Joan's tune the tune for the song in the DT, or is it of her own making?
