On a tram ride to St Kilda once, a normal-looking guy in a business suit got on and sat across from me. He was carrying a plastic bag that was obviously holding maybe 20 or so records.

I made the cardinal error of striking up a conversation. At the time I didn't own a record store - nor any Frank Zappa records, being a Beefheart kinda guy.

"Find any good records today?"

The "normal" guy proceeded to tell me every pressing he owned (Brazilian, Russian, Portugese, American, British, Australian, Canadian, New Zealand, Japanese... you get the idea) as he showed me each record in the bag.

They were ALL Frank Zappa.

"I think this is my stop" I said, slowly rising from my seat, backing away as I made sure he wasn't following me...
