Task: Question Generation
Input (English): Passage: From 1987 to 1992, Bill Drummond and Jimmy Cauty released music under names including The Justified Ancients of Mu Mu (The JAMs) and The KLF.  Following a run of five consecutive UK top-five singles, The KLF executed a high-profile retirement from the music business and deleted their entire back catalogue, declaring that "For the foreseeable future, there will be no further record releases from any past, present or future name attached to our activities."  Drummond and Cauty's subsequent art project, the K Foundation, disposed of The KLF's earnings, including by burning one million pounds of it, money which was originally provisionally earmarked by the duo for millennial celebrations. Bill Drummond: "Originally we were going to invest the whole lot in some capital growth fund and spend it all on one big event, maybe at the millennium".In the four years following The KLF's retirement, Drummond and Cauty's musical output consisted only of a limited edition single released in Israel and Palestine ("K Cera Cera"), and a contribution to The Help Album ("The Magnificent").
In 1997, British artist Jeremy Deller pioneered the Acid Brass concept, collaborating with the Williams Fairey Brass Band to interpret and perform classic acid house tracks as brass arrangements.  Deller was described by one source as a prankster, a notion frequently applied to Drummond and Cauty themselves.  In February 1997, Drummond was contacted by his former Big in Japan bandmate Jayne Casey, who was helping to organise an arts festival in Liverpool and had noticed that Acid Brass' repertoire included The KLF's "What Time Is Love?".  Drummond attended the festival performance and heard "What Time Is Love?" performed as the encore, during which he telephoned Cauty.  Cauty and Drummond together attended a 19 April Acid Brass performance at the Queen Elizabeth Hall, London.  Collaborative work ensued between Drummond, Cauty, and Deller, in which the Acid Brass rendition of their track was incorporated into a composition designed to mark the tenth anniversary of Drummond and Cauty's first work.
Output (English): What are the first names of the three people collaborative work ensued between?
