It was taped in the middle of the 29th season of Sesame Street, and features music video remakes of several classic songs from the show performed by celebrity guests.
The show is a musical that takes place at New York City's Radio City Music Hall, featuring performances from guests Jon Stewart, David Alan Grier, Rosie O'Donnell, Gloria Estefan, En Vogue, the Fugees, Kenny Loggins, Shawn Colvin, Jimmy Buffett and the Mighty Mighty Bosstones to celebrate Sesame Street's 30th anniversary.
Meanwhile, Grover, Susan, Gordon, Gina, Bob, and Mr. Handford get lost on the way to Radio City Music Hall, and they end up in Roswell, New Mexico, having picked up chickens, penguins and the Yip-Yip Martians as hitchhikers.
After the Muppets rescue the crew and Jon Stewart finally breaks out of the dressing room, they show a video of Kenny Loggins and Big Bird performing "One Small Voice" to motivate Elmo to come out of hiding.
