I'm about to go off to Heartland Opera which is collaborating with Missouri Southern State University on the 6th production of RSBE. Here's the video from last spring's 2021 production of RSBE at Amarillo Opera. The accompaniment is the two keyboard version which has piano and keyboard.
The Amarillo production changes the premise from the original version at the University of Alabama. This optional premise incorporates COVID into the plot in a more plausible way. Either premise can be used when producing the show at this point.
