@edgarblythe,
Well, edgar, you sent me searching again.
The Oak Ridge Boys are an American country and gospel vocal quartet.
The group was founded in the 1940s as the Oak Ridge Quartet. They became popular in southern gospel during the 1950s. Their name was officially changed to the Oak Ridge Boys in the early 1960s, and they remained a gospel-oriented group until the mid-1970s, when they changed their image and concentrated on country music.
It's Christmas time once again was great, especially that guy singing bass.
Thanks for your observation of The Other/Fourth Wise man.
Today is this Indian's birthday. I know the name, but not the man. Here is a tribute to him.
