This cover is a bit of a revelation. Who knew that this song even had lyrics?
In its original version, it didn't. Henry Mancini wrote it without lyrics, in support of the television series of the same name.
In the 1960, Jay Livingston & Ray Evans added lyrics. This version was originally recorded by Sarah Vaughan - in this version, the song is called Bye-Bye. The Jody Grind - an Atlanta band that released two albums in the early 1990's but disbanded when two of their members were killed in a car crash - covered THAT. Kelly Hogan's huge, soulful voice completely dominates the tune, and that's a good thing!
