Whose voice is it anyway

So Led Zeppelin are going to tour with a different singer, seeing as Robert Plant doesn't want to take part in it. Good for him I say, but surely without the trademark voice they're going to be a bit lacking. Just like "Thin Lizzy" & "Queen" have been of late. However there's a few options for who they can replace him with...

Chris Cornell - Made his career by trying to sound like RP and even spent most of the late 80's and early 90's trying out the long curled, bare chested screamer look - 1/2 favourite

David Coverdale - Hair: check, open shirt: check, Sexist lyrics: check, made a career of being a 2nd division Plantalike: check. Only thing stopping him would be that he'd want to appear on Loose Women again to plug the tour! - 10,000 (screaming middle aged housewives)/1

Sebastian Bach - Claims to be asked to join just about every band going, said that he was the 1st choice for Velvet Revolver and probably has auditioned to be in Black Sabbath, Iron Maiden and probably The Wiggles as well - 5/1 outsider

Gene Simmons - Not actually to get on stage with them, but to buy up the rights to the name and launch a local version of the band in every country going with all the members wearing facemasks of the classic line up and will claim the songs are relevant and it doesn't matter who plays them as long as they look vaguely similar - $50,000/1 investment

Terry Reid - He was the original 1st choice for the singers job when the band was first put together, but turned it down thinking he was capable of better things and was about to support The Stones on the infamous 1969 tour that ended in Altamont, not even famous enough to be the Pete Best of stadium rock! - 200 (album sales since then)/1

Juande Ramos - Well he needs a job! He'll be good for getting the European leg of the tour underway, but will probably learn a set of Boyzone songs and have to be replaced by Joe Kinnear or Harry Redknapp at the interval of the 1st gig - 2(points from 8 games)/1

Rick Astley - Well he's popular again and hardly out of the media these days, so it'd be a popular choice on YouTube! - 2/1 2nd favourite
