In episode #65 9-27-1974 " Ol Brown Eyes" Fred gets a ring supposedly belonging to Frank Sinatra. Each time he puts it on he flutters his hand and begins to sing. Does anyone know what song he sings? Is it a real song or just something he made up?

I think it was "If I Didn't Care" by the Ink Spots that Fred is singing in that episode!!! He also sings that in several other episodes!!!:) :)
