Maybe one day you'll grow up. Incidentally, I've seen Led Zep, Iron maiden (Adrian Smith's original band URCHIN were far superior BTW) Sabbath, Judas Priest, Whitesnake, Rush, UFO, Angel Witch, (many other NWOBHM bands too! Oh yeah, Angelwitch rocked!) I walked out the only time I saw Iron Maiden, they were on the bill with Judas Priest (what a waste of an evening that was!) Motorhead (my ears are still ringing from 1978 Lyceum) Hawkwind (not loud enough!)
