An appeal to HW/Lemmy experts out there. I just got 'The Best of Motorhead--All the Aces' a two-disc set. Well, not exactly. One disc is called 'The Muggers Tapes.'Supposedly, it was recorded in '78. The other disc is a compilation of 'Motorhead' tunes spanning from 'Bomber' to 'Orgasmatron.' Is this a re-mastering of old hits, or just an as-is compilation?
