Norah jones y.jpg

"Don't Know Y" is a Sesame Street parody of Norah Jones' song "Don't Know Why." This song is about her having planned a playdate with the letter Y (David Rudman), who didn't show up. As she sings, Elmo sees the letter Y showing up late. Elmo tries to tell Norah, but she is too upset to notice. However, she eventually realizes that the Y did come after all.

Later broadcasts of this segment include a post-roll, in which Norah, Elmo, and the Y all yodel. The segment appeared on Die lange Sesamstraßen-Nacht, a special Sesamstrasse late-night block.

The song was referenced in Sesame Street's 50th Anniversary Celebration, where the letter Y shows up after Jones' performance of "Welcome!" and they echo their lines from their previous encounter.


  • The segment was taped on December 3, 2003.[1]
