Big dilemma, song choice advice please... and just advice.

Here, at least, you can get a tax receipt for the value of your performance. So if you would normally be paid $250 for your show, you can donate that and receive a $250 tax receipt- the same as if you wrote them a cheque. You will likely have to provide an invoice stating the value of your service.

It might be worth asking about!

Great idea. That could be done legally in Australia too, I'm pretty sure. I must look into it. I think it's a great idea, not just for tax reasons but because it emphasises to the organizers that your work does have a value.
