Hello. Fellow trombone player here. I was doing the same stuff when I was his age. I remember my first concert like it was yesterday. If he sticks with it, there are plenty of great memories and opportunities in store.

Hah that’s amazing. Enjoy the moment papa!

The joke landed. 

I picked him up today and he said "dad, I made the whole audience laugh!"

My guy needs to grow up to be a stand up comedian.

My son's first band concert. He got to do a trombone solo/improv. He chose to make a fart sound.
