Definitely not me! :)
I wonder if there's somebody that's been to every single concert, but that'd be pretty near impossible to do, unless you just followed the band around the world for years.
I remember around the time of the Magic Tour a news report interviewed somebody who had been to see Queen an incredible number of times could possibly have been every show I'm not certain it was a long time ago! I seem to remember Brian & Roger were presenting the guy with some sort of award for his efforts!
Anyone else remember this?
