The TV special ‘Christmas in Washington’ featuring Mariah Carey and ‘Glee’’s Matthew Morrison has finally become available for the public.

The show was hosted by Ellen DeGeneres and attended by U.S. President Barack Obama and the first family.

Mom-to-be Mariah sang "One Child" and "O Come All Ye Faithful", while Morrison opened with a couple of verses from "I'll Be Home for Christmas" before segueing into "Mele Kalikimaka".

The show – which was taped at the National Building Museum in Washington, D.C. on Sunday, December 12 – also featured performances from Miranda Cosgrove, Maxwell and Annie Lennox.
