500 of them and some absolute crackers in there, my personal favourite is a farely recent Steve Lawler effort.

So tonight Radio 1, 1am til 3am will be the super secret 500th dj/act.

Hopefully it's not Pete Tong doing it himself, i think it's more likely to be a sasha and digweed or oakenfold back to back or something. Perhaps even Daft punk to have a go at bettering their highly regarded '97 offering.
