For Easter weekend on Radio 4, Paul Gambaccini's in the quizmaster's chair for a very special edition of the long-running music quiz, 'Counterpoint'. The quiz covers the usual broad mixture of musical styles - but all the extracts and musical clues in this special edition will be played live in the studio by the BBC Philharmonic, taking a breather from their current Mahler season of concerts. Answering Paul's questions, and identifying the extracts, are three musical celebrities - soprano and radio presenter Catherine Bott; conductor and comedian Rainer Hersch; and musician, writer and comedian Kit Hesketh Harvey. The BBC Philharmonic will be providing plenty of surprising arrangements of familiar melodies, from Tchaikovsky to Take That. You can hear which of the celebrity panellists proves to have the broadest musical knowledge in this unique collaboration recorded with an enthusiastic audience at BBC Manchester.
