"Oh, How I Miss My X" is a Sesame Street song sung by Patti LaBelle at a nightclub, singing about missing her letter X, with flashbacks illustrating their good times and relationship. After the song is over, the letter X appears from the audience, and she is reunited once again. Patti gives the letter X a kiss, and everyone applauds.
