I just made this versions a couple of years ago, basically it's the three single/edit versions that exist from the first album in great quality. I just take the best sounding versions that I have from the original tracks, and made the edits by myself, just like the original edits. This are the three:
01. Keep Yourself Alive (USA Edit single version 1975)
02. Liar (USA Single edit 1973)
03. Son And Daughter (Australian Censored Single Version 1973) link
I made the Liar US edit myself last week. I made the cuts at the right time using the album version and some of them are beyond understanding considering the butchering of the classic.
It came very good so i decided to keep it for my singles collection project i am working on. I'm gonna check yours...
