The Led Zep reunion - and, ready yourself to look surprised, okay? - might be more than that strictly one-off, no-more, that's it show. Jimmy Page slipped the word to Guitar World magazine:
"It's a bit selfish to do just one show. If that's it, we probably shouldn't have taken the genie out of the bottle."
Aha. Public demand. At least unlike the "public demand" which has resurrected Boyzone, this probably does have some routes in the actual public.
