In classic Bill Murray fashion, the comedian made a surprise appearance at Norah Jones’ Puss N Boots show in early December to sing the Elvis Christmas tune “Blue Christmas.”

Puss N Boots is Jones’ trio project with Catherine Popper and Sasha Dobson, and looking at the intimate crowd gathered at Sunny’s Bar in Brooklyn, New York, Murray’s drop-in was one definitely of those “only in New York” moments.

Murray is also a known Christmas aficionado. In 2015, the comedian debuted A Very Murray Christmas on Netflix, welcoming guests like singer Jenny Lewis and indie rock band Phoenix in a classic variety show format.
