To celebrate Christmas this year, CHAI delivered a cover of Wham!'s "Last Christmas".
CHAI's version of "Last Christmas" arrived on Christmas Day, and was accompanied by a video showing the Japanese group enjoying food and wine and Christmas festivities.
The group wrote in the video description, "Merry Christmas! Are you enjoying wonderful Christmas? How was this year for you? All the time including this year, next year, and even now this moment, is awesome and super fun! Let's enjoy togther! Love you!"
