Elmopalooza! is a Sesame Street 30th anniversary special that aired on ABC on February 20, 1998. 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.
At the beginning of the show, Elmo accidentally traps Jon Stewart, the producer Prairie Dawn, and the crew for the show in a dressing room when he closes the broken door, locking them inside. David Alan Grier doesn't take this well and constantly yet harshly rebukes Elmo for this mistake, and does the same to Telly for his neurotic behavior. The Muppets decide to produce the show themselves, with Elmo hosting.
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.
Despite a few malfunctions, the show goes on successfully as planned, until, during a duet with Elmo and Rosie O'Donnell, Elmo is accidentally sent flying towards backstage and straight onto Telly, Zoe, and Rosita, causing them to accidentally ruin the stage setting and shaming Elmo into running away and hiding, feeling he has failed to make the show better. 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. Elmo heads back on stage, feeling a lot better. Elmo, Grover, Susan, Gordon, Gina, Bob, Mr. Handford, and the cast sing a medley of Sesame Street songs at the end. Then, as the credits roll, the cast and celebrity guests perform "Can You Tell Me How to Get to Sesame Street?".
