@slaw,
I also have a 1973 Track copy of Quadrophenia (by the way, I saw the North American tour of Quadrophenia at the Fabulous Forum in Inglewood, CA. in 1974). It's in VG++ condition and sounds good. However, last year I secured a "new" copy of Quadrophenia on Classic Records 200 gr QUIEX SV-P vinyl. It was expensive, but damn, that is the best SQ of Quadrophenia I have ever heard. If you can find a Classic Records copy I highly recommend grabbing it.
