...which could be prog rock, soft rock, hard rock, Blackpool rock...anything really. Early spoilers are that Klitty is doing 'Live and Let Die', and Johnny is doing 'I believe in a thing called love' by The Darkness- nowt camp about that at all then!! Skanky Frankie is doing Primal Scream's 'Rocks'- very apt. 
The spoilers were very wrong early on last week though.
(Klitty, according to the spoiler is playing the piano- this could be her un-doing- a few years back Laura (?) who was really good, and an early favourite, was booted off the week she accompanied herself. We can only hope).
Someone will do Bon Jovi, I'm sure. And Coldplay.
Lets Raawwwk!
