The duo took to Canuck Place Children's Hospice, which provides palliative care to kids in British Columbia, with Canucks mascot Fin for some caroling outside the hospital.
Buble, clad in a Canucks facemask, and Petterson, sporting a throwback Canucks Flying Skate jersey, couldn't go inside due to the COVID-19 pandemic. Instead, they serenaded the kids, parents and hospital workers with delightful renditions of "Santa Claus is Coming To Town" and "Rudolph the Red Nosed Reindeer" from a safe distance outside before handing out presents.
Truth be told Buble did most of the singing solo -- much like his
stirring performance of 'O, Canada' during the 2020 Stanley Cup Playoffs
-- and we all found out why at the end of the video.
"I just realized I don't know any of the songs," Pettersson told Buble in the video posted to Twitter. "I don't even know the Swedish ones."
