This television special aired on PBS to join the fun. It's also slightly different to the one released on home video as "Sesame Street: 25 Wonderful Years". In it, it shows a blue sky background just like in Season 23 to 29 with Big Bird's voice-over saying the title before the theme song. Also, some of the songs are performed by various celebrities such as Little Richard. "Adventure" sung by En Vogue, "C Is For Cookie" sung by Marilyn Horne, "Rubber Duckie" sung by Little Richard, "The Letter O" sung by Queen Latifah, "I Don't Want to Live on the Moon" sung by Aaron Neville, "My Name" sung by Maya Angelou, "New Way to Walk" sung by The Oinker Sisters, "Monster in the Mirror" sung by Grover and some others, and "Sing" sung by Ladysmith Black Mambazo. The credits are also slightly different but longer.
Big Bird, Prairie Dawn and Telly watch as everyone expresses themselves with music, dance and other talents. Big Bird is reminded of a quote his Granny Bird told him, "The whole world is a stage." Prairie gets the idea to put on a show. Prairie assures them that their search will be an adventure!
They split up their duties - Telly and Prairie will look for dancers and musicians, while Big Bird looks for "la-la"-ers.
Telly and Prairie come across Jamal, Angela, Celina, Carlo, the kids and other Muppets singing an a capella version of "Do-Op Hop." They've found their singers for the show!
Big Bird has formed a "LA LA LINE" to audition la-la-ers. After a failed audition by Humphrey and Natasha, the Count steps up, not wanting to la-la, but to count those in line. Big Bird thinks his day will drive him batty, cuing the next song...
Big Bird's next audition is with a duck. The duck happens to belong to The Amazing Mumford, who knows a spell that will make everyone la-la. Although, when he tries it, the spell instead makes them quack.
Telly and Prairie report to Big Bird that they've found some singers. Big Bird responds he's having some trouble finding his la-la-ers. Telly wonders if it's as hard as finding a letter O...
Big Bird is glad Telly found is letter and wonders when he'll have the same success in finding la-la-ers.
Mumford tries his trick again, but makes people "baa-baa" like sheep.
Telly and Prairie now find a jam session going on and think they're the musicians they need. Elmo, playing the drum, comments that playing it is almost as easy as saying his name...
Elmo calls for a break and teases some of the highlights from the next half of the special.
Telly and Prairie ask Big Bird if he'd like to help them find dancers, but he's busy with his line. The next auditions don't do well, and Big Bird remarks he'll go bananas. Joey and Davey Monkey pop up at the mention of "bananas."
Prairie and Telly run into Jason and Savion while looking for dancers. Savion tells them that there are dancers everywhere in the park. Prairie comments at all the people dancing. "And pigs too," Telly adds, pointing nearby...
Big Bird shows Telly and Prairie Dawn the la-la-ers he's chosen - The Martians. He tells them they're going to become stars, causing the Martians to vanish for the stars in space.
The next la-la-ers in Big Bird's line is a man who plays accordion, while a chicken clucks. Big Bird begins to lose hope.
Big Bird's line is now empty. Mumford tries his trick again, but no one's around to be entranced by it.
Big Bird slinks over to a bench and begins singing "Sing" to himself. Ladysmith Black Mambazo immediately answers with a chorus of la-las, exactly what Big Bird's been searching for. Mumford tries his trick again, summoning all of Big Bird's friends to sing with him.
