Mei: OK, So, let's think first...
Me:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

The concert either involves multiple people dressed as Santa or one person dressed as Santa. It cannot be both.
Thus, the answer is no.
