On Friday night, Puss N Boots—the folk-rock trio comprised of Norah JonesSasha Dobson, and Catherine Popper—hosted their annual Christmas Extravaganza concert at The Bell House in New York City. The show featured all three artists onstage in holiday-themed attire performing a mix of country originals and Christmas covers in front of their hometown fans. To make the night even more magical, the trio was accompanied by one of their more famous fans, actor Bill Murray, who joined the band onstage to help Jones deliver a romantic cover “Blue Christmas”, originally recorded by Elvis Presley.

Bill Murray stepped to the microphone on the Bell House’s holiday-themed stage wearing an adorable little elf hat in unity with the band and their own outfits. Murray, Jones, and Popper all shared vocal harmony duties for the relaxed holiday tune, which had its own country swagger thanks to Sasha Dobson’s drum rhythm and Jones’ guitar work. Murray went on to encourage the crowd to join in on the collaboration (“If you know it you can sing along”).

You can watch Bill Murray’s sit-in in a video shared by a fan after the performance. The performance sounds pretty impressive thanks to the contrasting vocal tones of Murray and the two female singers. Bill shines just as brightly as those lights on stage when he dials into that higher singing octave to belt out the lyrics, “You’ll be doin’ all right, with your Christmas of white”. Check it out below:

However, Murray was not done performing with the ending of “Blue Christmas”. Buzzed on the energy of the holiday season, he also donned some reindeer bells and bounced around the stage like a little elf after drinking too much hot cocoa while the band played “Shake Your Christmas Butt”.

Friday was not the first time Bill Murray has shared the stage with the roots rock trio. The part-time professional musician previously sat in with the band just a week prior during a Puss N Boots performance at Sunny’s Bar in Brooklyn. Murray also took his own musical career to new levels in 2017 when he teamed up with acclaimed cellist Jan Vogler for a classical album titled, New Worlds. Murray and Volver, along with violinist Mira Wang and pianist Vanessa Perez, also spent much of the spring and parts of summer and fall 2018 on a global concert tour in support of the new release.
