On this bootleg is Lemmy/Wallis/Fox line up. On "On parole" is Lemmy/Wallis/Taylor line up except song Lost Johnny where is Fox on drums. On latter release you have bonus tracks with Fox on drums too, 4 more songs I think. In late 1975 they started to work on first album but Taylor comes in and Fox goes away, "he didn't have a bite" said Lemmy. SO Taylor did "Overdubing drums" and that's On parole album.
