This first UK press used mixed up stampers which results in the A side actually being B, and thus B being A.
On the subsequent press the hand etched matrix 'A' was over-stamped with BB and B was replaced with with 'AA' (the two letters being one above the other).
On this issue side A matrix has 'Jonz' on side A and 'Sound Clinic' on B. The next issue reverses this.
The the track listing shown here is as per the music - and the label (unlike the second press which has the sides mixed on the label)
This issue is on very thin vinyl, the subsequent release is heavier vinyl.
