You are a good person who think of others before yourself. The problem is that if it’s done for one, it has to be done for everyone who asks. There will simply be no time to play any songs at all. And those tickets you bought were to watch them play their songs live, right?
Another version of this question is “can they please email a video shout out/birthday card/call/show up? The answer is the same.
Thank you for your understanding. Everyone should have a friend who is as thoughtful and caring as you.
