"Death Disco" is a song by Public Image Ltd. The record was released in both 7" and 12" single formats with a "1/2 mix" of the song and "Megga mix" (an instrumental re-recording of "Fodderstompf" from First Issue) on the 12" version. It reached number twenty on the UK Singles Chart.
The song was released in an alternate version as "Swan Lake" on the group's second album, Metal Box, with slight changes at the end. The title change reflects the quote from Tchaikovsky's score that surfaces in Keith Levene's guitar part.
In his autobiography, Rotten: No Irish, No Blacks, No Dogs, Lydon stated that the song was written for his mother, who had died of cancer not long before. In a BBC TV news interview at 09:10 on 7 July 2010, he spoke of how his mother was treated badly by the church and that they would not give her the Last Rites in the hospital where she died. The song expressed his feelings about this as a kind of 'shout therapy'.
"I watched her die," he told Select in 1990. "She was tough, my mum. She asked me to write a disco song for her funeral. This was hardly happy stuff."
