Urgent help wanted to film a concert tonight

Hey dude! What with the weekend adventures I've got planned I might have to skip this. Usually I jump at the chance for some concert photography, but I'm afraid this one won't work out.
I don't have anything fancy, but if you wanted to borrow my 450D with 50mm f1.8 you could. It would do for some okay portraits in low light...

Thanks, but I am going there straight from work so won't go your way before...
