I listened to most of that interview this afternoon, and yeah Frank may have been kinda up-tight... but I'm sure he still likes performing the Muppets. He said a lot of nice things at Jim's funeral, Muppets Celebrate Jim Henson, and The World of Jim Henson,etc. And hey, during his free time he still performs Bert, Grover, and or Cookie Monster whenever he's on the Sesame Street set. I like talking to you guys, but just lighten up on him. He's getting older like all of us, and he's moved up in life to tons of better things. Even I( personally ) want to be more than just a puppeteer.
