I think I still have a shirt from High school somewhere...
There is NOTHING as pathetic as a middle aged man wearing an Iron Maiden T-shirt...
(Excuse me while I go remove mine ;)
I saw Maiden with Motorhead and Dio opening in the 3003 era. For any IM fans...if you have not yet seen them perform live, do so before they are gone. Believe me. It will be worth it.
