MAYBE, just maybe some parts of the 2007 issue are from another recording day.
I believe they gave three concert that period at the MSG, and I don't think that
every day they play the same length of songs, one day it's 12 min. the next day it's 14 min. or 10 min.
Listen to Moby dick, Dazed and confused they all are sleightly different than the 1976 issue.
So MAYBE one song is from the first concert and another song from the second or third concert.
