Anyone know the going rate for this? 

if its in VG+ or better condition then you can expect it to be hovering near the £600 mark tho to be fair there are so few of them around that collectors more than likely will snap it up at any price.... IMO its rarer than 'Use it' or 'Bad Breath' and i have not seen any changing hands on the public venues.... 

Thanks a lot Joxer. It's a Ex+/M- record that I might sell

It will fly out of your hands.... (if i had 600 knicker laying about i would take it now.... i dont so i wont  ).
