Here is a video of Caroll Spinney as himself. He uses both Big Bird's and Oscar the Grouch's voices.. When I met him, he talked to me about following my dreams, which to be a great puppeteer, just like him. He was really nice to me and we talked for a long time when I visited the Sesame Street studio in New York city.
Alan Murakoa works at Mr. Hooper's store. Alan was really nice, and he came over and talked to me during breaks. Here is a video of Alan on his very first episode of Sesame Street, when he was introduced to everyone.
