Ooh let's see now - I gave my copy of Noah's Ark Trap to Ship Dawdler a year or so back, but there's any amount of old Leader and Trailer stuff which isn't rare as such, just the rest of it lies buried in Harrogate somewhere... I do own several very rare Sun Ra Saturn albums, but I guess my most TREASURED slab of ULTRA RARE SOUGHT AFTER CULT vinyl is a copy of the original yellow-label Blakey edition of the first Back Door album with which I would not part for all the tea in ASDA. That it's also one of the finest albums ever made is a consideration too of course...
