I cant help with the mp3's - but I am a huge OJ fan.
In fact it was a reference to OJ's that made me buy the first smiths single before i'd heard it. the interviewer in the nme described them as being like "an even more romantic orange juice" which hooked me. I was at the time walking around grimsby - my hometown - wearing check shirts, cowboy string neck tie, shorts and a floppy fringe "like roger mcguinn's" a la edwyn. within a week of hand in glove i'd moved to a flattop, a thread of beads and a bunch of daffodils out my back pocket. fickle youth eh!
A good place to start is "the glasgow school" which collects all the postcard stuff together.
