I saw and bid on this 45 on eBay. It is definitely a boot, as the single was never officially released, and apparently the Floyd rejected the idea of including these rare tracks as bonuses on the 'Shine On' box set.

How is the sound quality? I have the songs already on my vinyl 'Unforgotten Hero' LP and a couple of boot cds, but the quality never gets past a 6 out of 10. Always a little flat.
