According to Cody Littlewood, who posted the video to YouTube:
bq. We were at a piano bar [Brandy’s Piano Bar in Manhattan’s Upper East Side] as it was closing down and the bartender stepped up to the mic and did this. He had been behind the bar working a full shift and shouting over the noise for several hours at least. The singer’s name is Joe Ardizzone and he also asked to give credit to the his great pianist Nate Buccieri.
