This album always brings visions of aluminum Christmas trees and this music blasting out of console stereos like these.
The Ray Conniff Singers were essentially the vocal relief between the Mantovani and 101 Strings instrumentals in the Name-That-Tune world of your typical "Beautiful Music" FM radio stations of the '60s and '70s. They were known for making "safe" covers of pop songs your parents could like.
This included disco.
They actually continued until the '80s.
