Christopher Cerf, who lost his voice at the time, later sung a portion of the song at the Brooklyn Public Library on November 21, 2009. He later performed the song live, accompanied by Ivy Austin (backing vocals) and Paul Rudolph (percussion), at the "Sing: The Music of Sesame Street" event at the Museum of the Moving Image on August 18, 2019.
- When the Beatles' catalogue was still owned by Northern Songs, the company attempted to sue Children's Television Workshop for $5.5 million. They cited that the song too closely resembled "Let It Be." Before the case came to trial, Michael Jackson purchased the Lennon/McCartney catalogue and the suit was dropped. The Children's Television Workshop was only fined $50, which was paid out of Christopher Cerf's own pocket. Paul McCartney, who was not involved in the lawsuit, wrote to Cerf saying that he liked the song.
- On the Count It Higher: Great Music Videos from Sesame Street home video, the segment has MTV-style captions that refer to "Lemon Records" (a parody of "Apple Records"), and also had an album name that would later be released onto CD five years later (Sesame Road); the lyrics to this song were released in the original release of the video.
