I would call the Box Office or wherever he got the tickets. You could try LCT website & contact us or call LCT administration. I don’t know of any miracle cures or ways to get a negative test from a positive one in just a few hours. (I mean these could be false positives) so calling or asking on line may be the best bet. Of course I had come in from Hartford this afternoon for Assassins, which was cancelled while I was on the subway to the theater. Theaters wait until the last minute these days, not wanting to disappoint their patrons and to salvage a performance if possible,
