The Punch Brothers have a semi-regular appearance at the Living Room in the LES at which they perform what they refer to as P-Bingo night. This particular one (#6) was special because it featured Sean and Sara Watkins of the former Nickel Creek.
Some regular fellow fans created the P-Bingo game, in which songs or covers are placed into squares and marked off accordingly during the show. This is the card of the first ever winner.
P-Bingo videos from this and other shows can be found on my YouTube channel.
