I don't know much about The Pair Extraordinaire, and neither does the interweb. I learned that they once toured with Bill Cosby, opening for him. That's about it. The Pair are Carl Craig on vocals and Marcus Hemphill on bass. Hemphill, if you follow the link, wrote for The Cosby Show and died in the mid-1980s at the age of 56. Don't know anything about Craig. This seems to be the only video of the American duo out there. They're pretty great, judging from this version of the Monkee's I'm a Believer and a couple other audio tracks I heard on-line. Not jazz, but jazzy and soulful. The clip is from the 1968 CBC Vancouver series, Hits A-Poppin', hosted by none other than Mr. Terry David Mulligan. Enjoy.
