That concert was overdubbed a lot in 1981, considering it was supposedly going to be released on the band's 20th anniversary. Nothing came of it, but the master created with the overdubs was used in 2002 (with Bruce omitting six tracks) when the official CD was released.
Parts of that concert were shown in the summer of '81, along with parts of the July 4th 1980 D.C. show, in their syndicated 20th Anniversary TV specal.
