Idina Menzel & Andra Day join Jennifer Nettles for festive album

Jennifer Nettles has recruited Idina Menzel and Andra Day to join her on her new Christmas album.

The Sugarland singer hit the studio with Menzel to record a new version of Little Drummer Boy, while Day joined Jennifer to tackle another festive favorite, God Rest Ye Merry Gentlemen.

Both tracks will appear on the singer's upcoming holiday album To Celebrate Christmas, which will also feature Nettles' take on Kenny Loggins' Celebrate Me Home and Irving Berlin's Count Your Blessings Instead of Sheep.

There's also a new song, Circle of Love, which Dolly Parton has written for her upcoming festive film Dolly Parton’s Christmas of Many Colors: Circle of Love.

The TV movie features Nettles as Parton’s mom Avie Lee Parton.

Meanwhile, Idina isn't new to Christmas albums - her own release, Holiday Wishes, was one of the hit holiday compilations in 2014.
