Today, a mix of Irish, French and French Canadian:
Chieftains - A Breton Carol (1987)
The Christ Child's Lullaby - Celtic Christmas
The "Huron Carol" (or "'Twas in the Moon of Wintertime") is a Christmas hymn, written in 1643 by Jean de Brébeuf, a Christian missionary at Sainte-Marie among the Hurons in Canada. Brébeuf wrote the lyrics in the native language of the Huron/Wendat people; the song's original Huron title is "Jesous Ahatonhia" ("Jesus, he is born"). The song's melody is a traditional French folk song, "Une Jeune Pucelle" ("A Young Maid"). The well known English lyrics were written in 1926 by Jesse Edgar Middleton.
This version is performed by Heather Dale, and sung in Wendat (Huron), French and English.
As noted yesterday there are too many Elvis impersonaters out there and some of them make fake videos pretending to be the 'King'
There is one however who made no secret of his copycat Elvis style and that was the late Les Gray of the pop/rock band called 'Mud' and you have heard the song every Christmas for as long as you can remember.
