No hurry to answer this - especially with the Revenue looming

When (and if) you get any free time, what sort of bands do you go and see. Are there any, for instance, that you would say "I must get a ticket to see so-and-so"?
Or is it a question (as with some of my musician friends) of spending so long at looking at things with a professional eye that one can't really enjoy the performance because of think "I wouldn't have done that" or "that didn't work" ....
Good luck with the return ....
