Despite Alvin's current fame/celebrity, which maybe was on the slide by now, this didn't enter the charts until 4th October and in two weeks peaked at No. 52.
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.
My copy looks the same as above but has a gold stamp top right corner saying:- 'Limited Edition special price'. Don't know when this dates from as I didn't buy near its release.
My side 1 has ALLEN and side two has JA etched in the run-off groove.
