Backstreets is actually around 11:30. the intro to Rosy is tacked onto the end of Backstreets. he talks to the crowd for a while asking about who attended the previous night's show. also some tuning issues. . .
excellent sound to boot. the mix is different than the circulating board tape of course (which IIRC had Steve pretty high in the mix). loved hearing him cranked up on that tape. but a near definitive version of the promise until he screws up the "followed that dream through the southwestern flats, dead ends and two bit bars" line at the end.
for the fans of audience noise and room ambience, unfortunately you will be disappointed. there is very little audience in the mix, almost none during the music.
