I was reminded recently about the time when I turned down Muse for a show. Of course, they weren't who they have become today, but that of course is why people like to remind me.
In 2000 I was booking a concert at Brixton Academy, part of the National Student Music Awards which I'd founded with a friend of mine. A CD arrived in our offices (a mobile office/shed) in Bournemouth. I put the CD on and thought it sounded like Queen, and as a Queen fan that should have been positive, but we decided to pass on the offer.
I wander if things would have turned out differently for them, if we had booked them. They probably owe me a favour.
Anyway, the obvious moral of the story is, if it sounds like Queen, book it.
