I had never heard of the singer, David Phelps, but I keep hearing him singing O Holy Night on the radio Christmas channels. I always like that Christmas song. What he does with this song is spectacular!
The orchestrations behind this song are marvelous. It really features brass, and it's glorious as is his voice. Stick with it to the end.
I now associate this song with Bob DiMucci, based on the post in which he wondered why the song was included on a Soul Hits of the '70s compilation. Disco is not something one might associate with Bob.
