Two questions about going to gigs with shall we say "selective appeal" and breaking the established norms of concert-going etiquette:

1. Have you ever walked out of a concert in the middle of a haedliner's set, despite the fact that the rest of the audience seem are enjoying it, because the artist/band is, quite frankly, rubbish?

and

2. Have you ever really wanted to see an artist/band, but been unable to persuade anyone else to go with you, and decided to buy a single ticket and go on your own anyway? If so, have you really enjoyed it?
