That date is wrong. There is no logic that this band would be playing SS, nor, revert back to an earlier working of a song (GDW, YMLF) after the album was out. Also, the setlist/performance/structure for the Philly 3-21-77 and the Paris 4-77 are nearly identical. The order may be different, though. That "4-1-77" show clearly does not fit in. Doesn't Stevie also introduce SS as being on the new album? This show was obviously from the previous summer '76.
