You've been to some damn fine gigs, though - and that's not just TF&TD :)
There are so many gigs where I no longer have the shirts or ticket stubs The ticket stubs used to be pinned to the wall above my bed, before I left home. Then they were slid into record sleeves or CD sleeves. Every now and then one appears, or as happened yesterday, an old Kerrang! article about Rush fell our of "Exit... Stage Left" when I played it to honour Neil Peart (aand then switched to Spotify as the digital remaster is waaay better than the 80s LP).
