I think if I were gigging at that frequency I'd want to be playing my/the band's original music and trying to build a career. At my time of life I doubt that I would have the stamina to do this given we have kids (albeit now living and working away from home) plus at the moment, some pretty serious health issues with Mrs ead.
I think you have a couple of years on me Blue and hats off to you for doing what you do, but I think I'm in roughly the right place with my work / life / music balance now. In my youth I did tour Europe playing violin in an orchestra to a pretty decent standard, but a symphony orchestra is a whole different thing to a rock band!
