for the record the sandman does not live in the uk or run any singarounds in the uk, neither does he run mudcat singarounds.
I never make negative comments on the mudcat singarounds, which are run by joe offer.
my advice about taking a note quote
however it is a good idea to know what note you start a song on when singing unaccompanied, if your voice happens to be iffy that day and there is a big range you can pitch a note lower., it is all part of trying to improve and take a more professional attitude.
my comment is about trying to improve performance and avoid embarrassing oneself and requires very very little formal musical training, IT WAS SPECIFICALLY RELATED TO OCCASIONS WHEN A SINGERS VOICE MIGHT BE IFFY DUE TO A COLD ETC.
