'Sesame Street' Fires Three Original Cast Members

“Sesame Street” has let go three of the show’s original cast members: Bob McGrath, Roscoe Orman and Emilio Delgado, also known as Bob, Gordon and Luis.

Watch the video above to find out why.

On Thursday, “Sesame Street” released a statement on Twitter:

McGrath, who has played Bob for the past 45 years, spoke about the firings and the show’s changes at Supercon.

“The show has gone under a major turnaround, going from an hour to a half-hour. HBO has gotten involved also,” the 84-year-old said. “And they let all of the original cast members go, with the exception of Alan Muraoka — who is probably 20 years younger than the rest of us — and Chris Knowings, who is also young.”
