Saturday Classics this week is presented by one of the BBC's great broadcasters. Peter Day has presented business programmes on BBC Radio 4 and the World Service for many years. Yet, he has an abiding passion for music, which has underpinned his life since childhood. Today, for Radio 3, Peter Day puts aside matters of finance and business to present two hours of his favourite classical and folk music. His highly personal selection embraces the musical worlds of Dvorak, Scarlatti, Monteverdi, Jake Thackray, Shostakovich, Mozart and Mahler.
