Pardon the intrusion but what does this have to do with Vocal harmony? (OP).........just sayin', LOL....and JUST KIDDING!!
Dave that was a great post which reinforced my last 50+ years performing so I must have been doing almost everything you mentioned and more. Thanx for speaking from the trenches with a heavy heart many hear will never experience it but I'm sure they understand what it is to put yourself on the line full time to make the audiences happy, support your family, and making a decent living for a very long time with enduring passion thruout......Love you man!!
Even though the Game is changing rapidly keep making them happy night after night!
