I was about to remove that from the list, because the quality on bandcamp really sucks. I don't recommend to buy it from there.The reason I didn't remove that is only because it's another (slightly different) version of the song Rock N Roll (the whole album is slightly different). So besides clean, there are 3 slightly different versions of the song Rock N Roll.
The version that I have from years has length of 06:22 and it has "different" in it's name, that's probably the version from promo CD and single. The second version on the bandcamp has length of 07:03. The CD and digital version has the length of 07:16.
I got all version, so if anyone want to compare them PM me.
