At the last minute his piano player canceled for just the preview so he and a buddy re-did the whole show with an acoustic guitar and yet everyone had a great time. This show with a piano hopes to be even more engaging. Knowledge of theater kid tropes and plays will make for more enjoyment but is by no means necessary
My overall impression
Musical gems and stories about autistic love make for a potent mix. George is charming performer who will make you feel like you have a snarky new best friend with pipes for days.
