2011 single by Mariah Carey and John Legend
"When Christmas Comes" is a song by American singer-songwriter Mariah Carey from her second Christmas album/thirteenth studio album, Merry Christmas II You (2010). Carey wrote and produced the song in collaboration with James Poyser. A soul song with influences of R&B, the lyrics are about giving the gift of love. In November 2011, Carey re-recorded the song as duet with John Legend, which was later released as a single. Both versions of the track were a hit in South Korea, with the duet debuting at number one with sales in excess of 80,000 copies. The song's accompanying music video features Carey and Legend hosting a Christmas house party. It has been performed by Carey at her ABC 2010 Christmas special and during her 2014 Beacon Theatre residency All I Want for Christmas Is You, A Night of Joy and Festivity in December 2014.
