NORMA

We got it from As I Roved Out Peter Kennedy's programme on the Home Service. Lal and I heard somebody singng it there so we never heard the somg as it's sung in Helston. It isn't sung the same. We got the words from somewhere, maybe the Society, maybe Tony Foxworthy, and we sort of remembered the tune as it was by these two old men who sung it on As I Roved Out. We put this tune to thise words but we didn't think it was complete for some reason so our Michael wrote that first verse, "Since Man has been created?". Now people sing it and they think it's part of the Helston song. It's not! In fact we've had people from Helston say "Why do you sing it all wrong?" {Laughter} It was because we didn't know how it was sung basically!"
