Did anyone say Classic?
this one is the release on FFRR, the original first release was on Philly Blunt.
On side one there's the two versions that each had their own side on Philly Blunt, and which i think do not need any introduction.
The B-side are remixes which seemingly function as mashed up versions for DJ-use.
not sure if this release was necessary, but undoubtfully people, including me, can be happen that it exists as the original release on Philly Blunt is not that easy to find, and without the existance of this FFRR release it would certainly not be any cheaper if you happen to find it.
