these types of dewy-eyed nostalgia acts usually go horribly wrong, esp when one considers the staggering amount of $ involved...forget it, not worth it in the slightest.
now, i could be tagged a bit of a hypocrite as i just forked over $340 for 2 neil young tickets, but there are a couple of key differences:
1 - the place he's playing is pretty small (2.5K)
2 - he's got a full band (i've seen him @ the Orpheum twice, but just solo)
3 - he's still on his game.
the last one is the most crucial. neil has never stopped recording good songs (well, at least sorta good), and tours consistently.
that's way more than you could say about van halen w/ DLR, the police, the eagles, etc - all those other classic rock dinosaurs for whom it's just a naked cash grab.
