I love Glenn's voice so much, I'm not sure I'd appreciate the idea of his tunes being covered by someone else. Having said that, I wouldn't mind hearing Paul Rodgers (ex Free and Bad Company), having a bash at some of the more bluesy numbers.
Re: Squeeze Covers?
I'd love to hear Busted doing ANYTHING of Squeeze's - the exposure would come in very handy (incidentally Busted did a cover of a Crowded House song on their latest single CD).
