Memorial is an epic funeral march-like piece, composed by Michael Nyman around 1984–1985. The work premiered on 15 June 1985. It was written to commemorate the deaths of 39 fans, almost all Italian, at the 1985 European Cup final between Liverpool and Juventus at the Heysel Stadium. The whole piece was performed just once. In 1989, Nyman began "reassigning" elements of Memorial, as he often does with earlier work. The first appearance on a commercial recording was of the fifth movement, on the soundtrack of The Cook, the Thief, His Wife & Her Lover. The piece incorporates and builds on a musical sequence from "What Power Art Thou”, an aria from the opera King Arthur by Henry Purcell.
