"Thanks again for a wonderful night's entertainment.
The songs were great, especially performing our first dance song live. We got such good feedback (and some of our friends are very musical and go to a lot of live music events). I thought we'd get a reasonable crowd dancing but was surprised so many danced so soon and for so long. You are really talented and I wish you luck with your music in the future.
We've already had friends from our wedding that are engaged asking for your details so we might see you at a future wedding!"
