DR singdaw, here's some photographic evidence (I have lots more) of the one-night High Covid Era (Sept. 2020) performance of ASSASSins by the theeder company that had put on a stunning production of it a few years prior. They rented the one remaining drive-in in that area for one night, set up every scene on the flat beds of pickup trucks - including a few nice vintage ones - parked along the front, and using multiple cameras, projected the show onto the huge screen. Spectators viewed from their cars just as they would a movie, with the audio piped to the car radios.
Miraculously, they were able to assemble all but one of the original cast. The only real concession was using a 4-piece band instead of the full orchestra used previously. As DR John G. indicated, the evening's big surprise was that the car parked in the front row - next to the band - had Stephen Sondheim in it. They allowed his car to pull out before letting us all know.
