Captial Q and King Lou were just a couple of friends from Toronto who came together to sample an old Quincy Jones song that was a television theme song. I suspect it is this song that caused "Soul Bossa Nova" to be the theme for the Austin Powers movies, although Mike Myers is Canadian, so he'd probably have seen the Canadian game show Definition.
And now you know where the chorus for this song comes from. And why the song has such a long title.
In case you were wondering about Definition, here's a 1982 episode. YES, that's the guy from Card Sharks.
