Edna (Beguine)

From Tardis Wiki, the free Doctor Who reference

Edna was an elderly resident of a retirement home. She and the other residents, including Ben, escaped one day to an old shack so that she could perform a strip show, despite not being particularly attractive or able to dance well. The show was broken up by a group of young people and the old people were taken back to their home. (PROSE: Beguine)
