Alright so this video is funny NOT BECAUSE IT'S AWESOME that he crashed their choir, but because FOR THE MAJORITY OF THE TIME NO ONE REALIZES IT IS HIM IN THAT CHOIR.
For a good minute or two, the kids DEFINITELY HAVE NO IDEA WHO HE IS. Then as someone shouts "Ladies and gentlemen Lennie Krivitz" the lightbulb clicks.
Damn young people...
Many did recognize him though, and this video is STILL awesome.
