When Big Bird throws a birthday party for his favorite teddy bear, Radar, everyone's invited -- and the residents of Sesame Street come out in droves to boogie down. The set list of sing-along songs (and corresponding dances with easy-to-follow movements) includes "I'm a Little Airplane," "Doin' the Grouch," "A New Way to Walk," "Birdland Jump," "Do the Jelly" and "Cat Had a Birthday."
