I think most bands are, although many gigs today use pre-recorded bits. Sometimes bands sound better when they've recorded in a studio and any bad parts've been altered, but you can't beat the atmosphere of seeing them live on stage.
I was only quite young - 11 or 12. I was having a fun day at the festival with some relatives of mine, and then it started raining so we were sheltering near the side stalls. I could've easily missed him because there was so much to look at and so much else to listen to. I caught Cliff for about 5 minutes, but at least got to the front and saw Floyd in all their glory. : )
did you manage to stay awake?
Ha, you'd be better off making daisy chains...
Elton is really worth seeing though, great songs and pure fun.
If you are lucky though Reg will have a hissy fit about whatever's riling him..
