I'm sure there are things you like or dislike about each player pro/con, stage presence, dress, playing style, presentation, equipment used, song selection, etc, etc, there are no rules,..I always said watching others perform is a true learning experience,....absorb and recreate,....everyone learns from each other out there!! Here's myself jamming with Joe Lee on guitar (RIP), Joe Ayalla keyboard, (RIP), with Don Mason & Hank (RIP) in Shreveport, Louisiana at the jam about 8 years ago so much fun and yes I learned alot from all these great musicians also, hope to do it again soon....
