This morning I'm wondering at what age you're too old for rock concerts. I'm pretty sure I've got heat exhaustion, I can't hear anything, I've got a strained voice and a complete inability to lift my arms above shoulder height. And a few general aches that come with two solid hours of dancing.
Worth it? You bet. Bon Jovi are professional rockers and they put on a really great show. I can't wait till they come round again.
