Sia Sings about Songs on 'Sesame Street': Watch

Sia arrives at the 15th Annual Trevor Project Benefit held at Hollywood Palladium on Dec. 8, 2013 in Hollywood, Calif.  

The letter “S” is for Sia, songs and, of course, Sesame Street. The Aussie singer and songwriter connected all the dots in a musical sequence on the long-running educational program.

With a little help from Cookie Monster, Elmo, Grover and their furry little friends, Sia tackled a subject she knows a lot about in the ditty “S is for Songs.”

“S is for songs, and I love songs. Don’t know what we’d do with out them/I love songs so much I wanna sing a song about ‘em," she sang.

Sia, who happily clowned around for her spot wearing bright colors and a red nose, joins an illustrious lineup of musical guests who’ve appeared on the PBS show down through the years, from Destiny’s Child to Johnny Cash, One Direction, B.B. King and many more.
