Congrats to this Williamsville, NY, choir on this once-in-a-lifetime opportunity they had over the weekend. It's not everyday you get to sing in front of 50,000 Buffalo fans with Mick Jagger as your band leader.

The choir from Calvary Episcopal Church in Williamsville helped The Rolling Stones Saturday night. According to WBFO, Alex Benestelli from the choir said:

I think everybody's knees were shaking a little bit. We're really appreciative of all the love from everyone out there in Buffalo that has supported us."
