Jackets, Tuxes, Ties are so restrictive and hot on stage, I hate them...I gave up those looks years ago... Appearance is just a minut part of the show...you must be comfortable when you play & sing all night. fancy Tux vests, open collar dress shirts, Hawaian shirts in the summer is more my thing...If its a Black Tie affair then I go Black Tie Arggg! Looking good will not protect bad playing... but will compliment the total success of a good musicians show.
