Subo and Macca are 'Gleeks'

The list of celebrities jumping on the Glee bandwagon is growing longer by the day.

Susan Boyle and Paul McCartney are the latest names to be associated with the hit TV show.

Subo's set to appear in a Christmas-themed episode - playing a school dinner lady.

And some of Sir Paul's music will be featured, after he wrote to the show's creator suggesting his songs be included. Glee creator Ryan Murphy says he thought someone was playing a practical joke when a fan note from the former Beatle arrived on set.

Sir Paul enclosed a mix of some of his songs in the hope that they might be used on a forthcoming episode of the hit show.
