The Secret Policeman's Ball
The Secret Policeman's Ball is the collective name for a series of charity performances featuring big-name comedians and musicians, held at various London venues, and once at a Nottingham television studio, to raise money for (and awareness of) Amnesty International.
Performances
All of these performances were filmed or videotaped and subsequently released to cinema or video. More recently they have been available, together with a compilation of musical items from the various shows, on a set of region zero (international) DVDs entitled The Secret Policeman's Ball: The Complete Edition.Source
