Hmm I haven't personally listened to any versions of the songs that go by those specific titles, but I know that "Buddha With Mace" was the early working title for Forget Myself. From the LOTFW warm-up gig recording, "Buddha with Mace" had a slightly different bridge in the middle of the song as compared to "Forget Myself".
But again, I haven't actually heard of those titled song versions so I don't know if they're the same or different to the album versions... Maybe someone else on the board has? Or you could just risk buying it to find out!
