Does anyone know who played the theme songs to the Cosby Show and/or the show Roseanne. The Roseanne show always had that raunchy tenor blues sound in the theme. The best Cosby show into is when Bill Cosby is wearing a tux and it's a black stage with each star dancing individually. Knowing Cosby's love of jazz and blues (who can forget little Rudy coming down the stairs singing "Baby" in Brother Ray's "You Know The Right Time"), I wouldn't be surprised if it is a "big" name. Anyone know?
