I'll pay to see a big name show in a large venue if there's any inkling of the band never coming round anymore. That's why I drove to Charlotte to see Iron Maiden a couple of years ago. I doubt I'll be given that opportunity again.
Other than that, I've seen enough good shows in sheds, and arenas over the years that I don't have the jones to keep up with who is coming round anymore. Plus the expense, and the parking, AND the crowds, AND the traffic... yeah, forget that noise!
