Hi Dave, If your 3 versions are like the one's which I filmed at the Lancaster Maritime Festival in 2004, then they are all different. It's not that they forget the words or anything, they just change bits here and there.
Try not to run into any young drunken hooligans this year as well, or just in case get those toe irons sharpened and set.
Congratulations on your promotion to Dave MD, break a leg.
Regards to all JohnB
