Kevin performed Clifford MuppetFest back in 2001 as well. Also Clifford isn't seen in It's a Very Merry Muppet Christmas Movie, but only a photo can be seen of him backstage.
i often wonder if maybe Clifford had a shot in the Muppet group shot when Kermit was telling them all about defering their paychecks, if maybe it the movie seen in widescreen? i don't know maybe not..just a thought, lol there's some other deleted parts of that movie that we still never got to see such as Sal dressed in drag in the night club and Fozzie having a joke about cream pies. bits of both can be seen in making of the movie Pepe feature on the DVD. It was good to see Cliffored even thought it was brief in the muppets Wizard of Oz, as the last time he was seen was at MuppetFest.
That was actulay the last time Dr. Phil Van Nutuer was seen as well other then his Family Fued aprerance. I miss him! well at least we got action figures of both characters.....won't mention Bobo,Sal, Bean, or Foo foo...whoops already did.

sorry off topic. But I've grown to like clifford more over the years.
