There is a jazz song that is being played at the end of the birthday blues episode and during the "smooth contest" in season 2. Does anyone know what it is? Cliff is dancing with birthday cakes in the blues episode, and the smooth contest is when Claire broke her toe. I have been looking for the title and artist of this song for a while.

I have also been searching desperately for the fantastic instrumental that is played at the end of episode 120, birthday blues. Can ANYONE offer us clues??
Thanks
