QUOTE No point?
I think she meant that it could have been any episode the crew could have put Al into. The plot wasn't dependent on Al's appearance.
It seemed as if no matter how they used him, they wanted to do right by the appearance, regardless if it fit into the show. It would have been really easy to just wedge him in somewhere in passing to say just a line or two, but doing a song? Bringing him back out during the credits? Animating four other guys that a good chunk of the viewing audience wouldn't recognize?
This was utilizing Al to the fullest for what was correctly stated to be just a cameo.
Now the big question is, any chance the song will turn up on any kind of silvery five-inch electronic plate?
