I just read in an old copy of 'Record Mirror' that the 12'' was being released on the 12th Jan' '79. Maybe they got the info slightly wrong and were referring to the 2nd pressing?
My copy is in a plain black die-cut inner and the 'Hot Biscuit' sleeve and has the 'number one... no less' etched in the run-off groove.
First release on the Wight Vinyl label and first vinyl release for grunge pop rock trio Panda Swim. Pressed on white vinyl only, comes in plain white die-cut inner sleeve. Available from AAA Records, Newport, Isle of Wight.
