Here is a question that I want to know the answer to but I can't imagine who to ask. I know that, for example, when Kermit and Fozzie record for an album or something that, um, Kermit and Fozzie don't go to the studio. By an amazing feat of special effects, a man named Steve Whitmire is able to project Kermit's voice so Kermit doesn't have to show up in the, er, flesh. In Fozzie's case, a man named Eric Jacobson is able to channel his voice so Fozzie can stay home and hibernate.
Is this phenomena also true when there are radio appearances? The reason I'm wondering is that it would be harder, I truly believe, to interact with someone that SOUNDED like Kermit but didn't actually look like him than it would be to interact with Kermit in an APPROPRIATE way.
Do you see what I mean? It's one thing to be sitting down with--literally--an American icon who you've seen on Sesame Street and doing both children's and adult's programming for years, and quite another to sit down with a guy who's been cracking wise with you in the lobby.
