Berkeley's compositions include an oboe concerto (1977), an oratorio "Or Shall We Die?" (libretto by Ian McEwan) (1982), "Gethsemani Fragment" (1990), "Twenty-One" (1991), an opera "Baa Baa Black Sheep" (libretto by David Malouf based on the childhood of Rudyard Kipling) (1993). Orchestral works include "Secret Garden" (1997) and "The Garden of Earthly Delights" (1998) plus concerti for clarinet, oboe, and 'cello. In 2000, Berkeley wrote his second opera, "Jane Eyre" (libretto also by David Malouf), which was premiered at the Cheltenham Music Festival by Music Theatre Wales and subsequently toured around the UK. The original drafts for "Jane Eyre", representing one year's worth of work and the only copy of them, had been stolen from outside his London home in May 1999. The manuscripts were never recovered, and Berkeley re-composed the opera completely in one year's time, for performance at Cheltenham.
