The 1970 performance of Albatross is on Spotify. I just listened to that on my phone while listening to the Warehouse recording on my laptop. They are 100% the same performance. With that confirmed... Why omit the best performance of that set? "I've Got a Good Mind to Give Up Living" (AKA "All Over Again") from this show has long been considered one of the best Green performances ever recorded, and would be a selling point for the set.
