This show was actually performed at Assembly Hall in Bloomington, Indiana, not Illinois.
A common enough error, but since this was the only show they ever played in my home of Bloomington Indiana, it is important to me. The show featured a lot of tuning up, leading to pleas of "time to get to work, boys" from impatient audience members sitting near me, but they caught the beam in the second set with the first Peggy-O I'd heard and a long Playing in the Band sandwich.
