HI,
In Season 2, the show "Second Time Around" when Bill breaks up with Charlene. At the end of the show, they dance in the airplane

It's Charley Pride... and he did two songs in the episode.

For more information, visit http://www.topthat.net/DWT/Music/index.html. GREAT source of DW information.

Thanks for the info but it isn't what I wanted.
I had checked out that website. And the two songs are by Mickey Giley and not the one I am looking for. There was a 3rd song, at the end of the show when Charlene and Bill dance in the hanger.
