As I understand it, it's generally agreed that the old Nippon Connection ROIO LP featured "One of These Days" and "Fat Old Sun" from the BBC Paris Theatre, 30 Sept. 1971. But even taking into account different versions' recording quality, if you listen to the first verse of "Fat Old Sun" from the LP, Dave sings: "When that fat old sun in the sky is falling, summer evening birds are calling. Summer Sunday and a year, the sound of music in my ears" (8:47-8:58 at https://www.youtube.com/watch?v=5gwUa6qkqF0&t) while a clean version of the 30 Sept. 1971 Paris Theatre show clearly reveals the fourth line as "the last sunlight disappears" (1:48-1:52 at https://www.youtube.com/watch?v=rijUeK8pejg).
I'm sure there are numerous other differences throughout the 15-minute performance, but I stopped there.
So, which show did the Nippon Connection version actually come from? Any help would be appreciated, and please let me know if I'm off-base or confused here!
