Had to download it...I am sure DFU can rework the lyrics to include busses, Lake Nagin, and Mayor Blanco
At the end, he clearly says HERE COMES THE TWISTER....maybe that is what the swinging arms means.
How about a different song:
The wheels on Jabbar's bus go around Round and round, round and round. People on his bus could get around Far out of town. The city's other busses, blub blub blub, Blub blub blub, blub blub blub. Nagin on the sidelines, blub blub blub, Watching them drown.
