Well I just can't remember the complicated formula that is used to calculate Easter Sunday! However I am certain it falls on different dates every year! It is not then impossible for it to fall on St George's Day as our English Patron Saint's Day is always on the same day. So although I have not read "English Folk-Rhymes" I would say that never is a bit of a sweeping statement. Not that it matters as the calling on song that is on the Rombalds Mummers Web Site is based on a Traditional Mummers play from Kirby Longsdale. As the Play was brought up to date (as were the original play's) by poking fun and having a go at Nuclear Power, The Pollution of our Sea's and Beaches by Oil and the erosion of our National Health Service for Private Health Service's. The calling on song was also adapted to fit the play more years ago than I care to remember. I do remember having performed the play 10 years before the Chernobyl disaster! I would suggest that until the message gets through you could sing it on any day and it would be relevant. "So lets leave the factory and leave the forge and dance to the New St George" :-)
