Yeah, it's just an EP, so listen to it, decide if it's worth bothering (the above YouTube appears to be the actual vinyl -- I only just learned that about the performances being different, but I grew up on that EP -- that's what got me into later Roxy Music -- so it holds a special place in my heart, and explains why I didn't feel I'd heard those particular performances recently) -- I doubt it, a lot of fondness comes from familiarity, IMHO. I think the other available performances are perfectly good, too, and have grown to like them (just like the difference in sequencing on The Name of this Band is Talking Heads -- I am now quite fond of the CD release).
