Okay, here ya go...and keep in mind that all of these people are STILL LIVING, so we haven't really "lost" them totally in my opinion. FRANK OZ--Has retired from all his Muppet characters, but I understand he occassionally goes in to the studio and performs a character if Eric Jacobson (his replacement) is out. JERRY NELSON--has retired with the exception of the Sesame Street characters. He is still active on SS performing The Count. DAVE GOELZ--Still actively performing for the Muppets as Gonzo, Bunsen and others. He has also taken over as Waldorf. STEVE WHITMIRE--has been performing Kermit and Ernie since Jim Henson's death. He also still performs characters such as Rizzo the Rat. CARROLL SPINNEY--Is still performing his two Sesame Street characters Big Bird and Oscar. MARTIN P. ROBINSON--Performs Telly Monster, Mr. Snuffleupagus and Slimey the Worm. FRAN BRILL--She was the first female Muppeteer hired for Sesame Street and has been actively performing Prairie Dawn and Zoe Monster, among others. DAVID RUDMAN--a Muppeteer from the early years, he is currently performing on Sesame Street as Baby Bear and has taken over Cookie Monster since Frank Oz's retirement. KEVIN CLASH--Plays Elmo, of course, plus other Muppets like Clifford. NOEL MACNEIL--another Muppeteer from the earlier years, he is best known as the big shaggy host of Bear in the Big Blue House. PAM ARCIERO--performs Grungetta on Sesame Street. KAREN PRELL--is now working at Pixar as an animator, but played Red in Fraggle Rock. I am sure she will be returning for the new film. Hope this helps you.
