mogenst, do you have either of these releases? your comments lead to more questions than answers.
I have the issue with picture from top here; gatefold sleeve with two glamour studio pictures in the middle. DLP 2-783 is only on the rear and the spine.
The two records have the AR numbers you quote; (so what are the 'different numbers' ??).
Looking at the All Round Trading discography it shows earlier single album releases of
AR 31035 called 'Dynamite' and AR 31036 called 'Ready Teddy', so my biege sleeve double lp would be a mere (quick) cash-in (re-)issue.
However date on (only) rear cover is 1985.
This bootleg double LP was released in Denmark with two different covers - and different catalogue numbers.
There's a Picture of the second release here, too.
The catalogue numbers of the second release are AR 31035 and AR 31036. The two LPs inside have different numbers!
