It omits the repetitions necessary in the actual opera. Anthony Burgess, writing in The Listener (magazine) in 1964, stated: “The excellence of Peter Grimes has a great deal to do with Montagu Slater's libretto, the only libretto I know that can be read in its own right as a dramatic poem.” He also wrote the libretti for `Yerma’, composed by Denis Aplvor. Slater was involved,
W. F. Grimes in 1959, and he became the third husband of Audrey Williams. She bestowed on him the nickname Peter. They retired to her home in Brynmill in Swansea in 1973. After Audrey died in 1978, he was remarried to Mrs Molly Waverley Sholto Douglas in 1980. He suffered from Parkinson's disease in later life, and died at home in Swansea.
