Two versions of this release exist, each with identical labels and runout etchings. The difference is heard on Part II, where Version 1 lacks the pronounced percussion and urgent energy of Version 2 (which is also the mix found on the national Wand issue). One must play the 45 in order to determine which version is present, as there is no visual difference between the two on the label or in the runout matrix.
You can tell the difference between the 2 versions by looking at the size of the run-in groove. If the size of the run-in is the same on both sides then it is version 1. If side 2 run-in is wider then side 1 then it is version 2.
