"The Official BBC Children in Need Medley" is a single by Peter Kay's Animated All Star Band. It is the official Children in Need Single for 2009, and was released on 21 November 2009. The song was shown for the first time on Children in Need 2009. The cover art is a parody of the cover of Sgt. Pepper's Lonely Hearts Club Band by The Beatles. The single has sold over 452,000 copies in the UK, earning it Gold status from the BPI.

According to a news interview, Kay conceptualized the single while working with the director. The director said that he would "love to do something like that" but he and Kay regarded it mostly as a joke.

After some time away from the subject, Kay brought it up again, this time with the actual intent to produce it. The director said that he and Kay "just sat down one lunchtime and wrote a list", with as many characters recorded on it as they could think of from their childhoods, as well as some modern favorites and non-British characters. The song was recorded at Hullabaloo Studios by the Voice and Music Company.

The project was carried out in top secret at the request of executive producer Kay. Celebrities and voice artists who voiced characters' original vocals were brought in without being told details of the project. When contacted by Cartoon Network Studios, Casey Kasem agreed to take part on the condition that Shaggy was shown to be a vegetarian and asked not to be given credit as he was officially retired.

The project took 132 hours to mix the vocals of the seven different songs, eight months to animate, and around two years in total. Many of the original character models had been packed away, given to museums or burnt. Where possible the originals were found and transported to Chapman Studios in Altrincham from all over the world. In cases where the original models no longer existed, such as the characters from Camberwick Green and Trumpton, new ones were created.

Because permission was not given by Royal Mail to use their logo, Postman Pat's van was a modified model with no logo.
