Radio 3 Requests - Beethoven, Chopin

Does classical music need more happy performers? Amongst Chi-chi Nwanoku's requests this week, one listener's plea for musicians to follow the example of Daniel Barenboim, Jacqueline du Pré and Pinchas Zukerman in their joyous recording of Beethoven's 'Archduke' Trio. Plus, virtuosic Chopin from a new Japanese piano sensation, the choral music of American composer Morten Lauridsen, and baritone Christopher Purves on a hidden passion for the music of Engelbert Humperdinck.
