Well, since you appear to be the best dressed of us and have the stage experience, you get to be the manager of this group, too!My stage costume? Same as I wore at any other time and you can see an example in the video I posted playing with my band on TV. For years I favoured collarless shirts, black jeans and boots or shoes with a slim lapel dinner jacket. I bought most of my clothes used from charity shops and the dinner jackets were particularly good value being ex hire and in perfect condition, it would be a full tuxedo but I discarded the trousers and the whole could be purchased for less than $5.
These days jeans and t-shirt on or off a stage.
