Democratic nominee Kamala Harris said on her campaign's X account that Trump rambled and "looked confused" on stage during the event.
Almost 30 minutes into the town hall event, Trump paused the event so someone in the audience could receive treatment.
Two minutes later, as Trump faced the fifth question of the night, another person became ill and the song played again.
Kristi Noem of South Dakota asked Trump on stage, "Do you want to play your song and then greet a few people?"
A national NBC News poll on Sunday put Trump and Harris neck and neck among registered voters, with three weeks to go until election day.
