OOOOOhh,. that works in church too - especially when doing something that was learned by ear first.... we discovered that we'd been singing something wrong for years, took ages to relearn it and then the composer went and rewrote it as the learned version, because as he said, that's the way everyone sings it anyway. It also goes the other way, learned a song from a book, sang it in front of the author, only to have him say 'that isn't what I wrote'. We showed him the score and he realised that it had been printed wrongly all along!!
