In 1978, Sting collaborated with members of Hawkwind and Gong as the Radio Actors on the one-off single "Nuclear Waste". In September 1981, Sting made his first live solo appearance, on all four nights of the fourth Amnesty International benefit The Secret Policeman's Other Ball in London's Drury Lane theatre at the invitation of producer Martin Lewis. He performed solo versions of "Roxanne" and "Message in a Bottle". He also led an all-star band (dubbed "the Secret Police") on his own arrangement of Bob Dylan's "I Shall Be Released". The band and chorus included Eric Clapton, Jeff Beck, Phil Collins, Bob Geldof and Midge Ure, all of whom (except Beck) later worked on Live Aid. His performances were in the album and movie of the show. "The Secret Policeman's Other Ball" began his growing involvement in political and social causes. In 1982 he released a solo single, "Spread a Little Happiness" from the film of the Dennis Potter television play "Brimstone and Treacle". The song was a reinterpretation of the 1920s musical "Mr. Cinders" by Vivian Ellis, and a Top 20 hit in the UK.
