This 12" actually has 4 tracks (maybe it's just my copy?) I'm thinking "Gutta Perch" is actually B1? All I know is the 2nd track on the A side sounds very much like "Griller Warfare" from Cylob off the "Lobster Tracks" EP, but I haven't listened to the two versions closely enough to tell if it would qualify as a remix. If it is, it is extremely close to the original.
