Four poets salute the centenary of W H Auden's birth.
He explores the distinctive nature of Auden's poems and how they work, with samples including The Fall of Rome and The Shield of Achilles.
Peter Porter explores Auden's plays and libretti.
He looks at The Dog Beneath the Skin, written with Christopher Isherwood, and the libretto of Stravinsky's The Rake's Progress.
Porter believes that in addition to Auden's stature as one of the 20th Century's finest lyric poets, these works guarantee his place among the finest dramatic writers.
