The song is listed in Mariah's November 2 holiday album 'Merry Christmas II You' and becomes the only duet track in it.
Following the release of lead single "Oh Santa!", another song from Mariah Carey's upcoming album "Merry Christmas II You" is unearthed. It's called "O Come All Ye Faithful / Hallelujah Chorus" and features Mariah teaming up with her mother Patricia Carey.
Mariah sings solo with full back-up of a gospel choir and is not joined by Patricia until halfway through the song. The opera singer then takes over the lyrics and belts them out in her towering voice before Mariah comes back to finish the lines.
"We discussed doing a duet and I really wanted to make sure it happened on this Christmas album," she said. "So I feel really blessed to be able to have this opportunity to have this on record forever - a song with my mom. She's the one who really got me into being so festive at Christmas. She's very festive as well!"
Patricia Carey is the only featured guest in the follow-up to Mariah's 1994 "Merry Christmas". The album will be on sale in the United States starting November 2.
