Yes this was years ago. From my recollection, if you have the Japan disc, you got the extra tracks from the Flashlight Tour stuff that was on the other two versions. Cosmic Slop was on the J version I know. I have to check the cassette to see what else is on it.
OK I’m back. From what I gather it’s basically the rest of the Flashlight gig recorded at Hampton VA in the spring of 1978. A friend of mine has the Japan version and put it on a cassette. What I have labeled on the cassette is
Cosmic Slop
Maggot Brain
Bop Gun
Flashlight
Mothership Connection
Tear The Roof Off The Sucker
Night Of the Thumpasaurus
Even though I think Bop Gun, Flashlight, Funkentelechy and Starchild was on the other versions. Funkentelechy is not on the Japan version but is from the same concert. Cosmic Slop, Maggot Brain and Give Up The Funk is exclusive to the Japan version. It has been many years since I looked at any of it. The cassette I have also has some Funkadelic tracks from the Sugar Shack '72 but I don’t know what until I listen to it later.
