A key moment in Sesame Street's history was the release and marketing of the show's educational and entertaining musical content in the form of albums and singles. "Hello" was an audio skit featured on the first Sesame Street single released in 1970. The skit introduces the main street characters to listeners who may not be familiar with the show or its characters. This rare skit was included as the B-side to the Sesame Street Theme Song on a 45 single (CC 75001) and has never been made available or re-released on any other album or single.
