Mariah Carey's "All I Want for Christmas Is You" has taken the lead over Tom Grennan's "It Can't Be Christmas" in the race for the U.K.'s Christmas No. 1 Single, according to the Official Charts Company. The festive classic, celebrating its 30th anniversary this year, is now in pole position to challenge last week's chart-topper, Wham!'s "Last Christmas." Grennan remains at No. 3, with Carey's hit single setting a new chart record for spending the most weeks in the top 40 before reaching No. 1 in U.K. chart history. Grennan, who got a tattoo in honor of the chart battle, is one of several British acts who have recorded Yuletide-inspired tracks for Amazon Music U.K.
