Tom Service talks to pianist Imogen Cooper about her life-long passion for the music of Schubert, which she has been re-visiting in a series of performances and live recordings at the Royal Festival Hall, 20 years after she made her first complete survey of his piano works. He visits Cambridge, ahead of a week of choral concerts marking the university's 800th anniversary, to explore the past, present and future place of singing in the city. He also discusses the role of music in cancer care with Don Campbell of Mozart Effect fame.
