BBC2 joins with Radio 3 in stereo for a live relay of the first half of tonight's Henry Wood Promenade Concert from the Royal Albert Hall, London. The Royal Philharmonic Orchestra, leader BARRY GRIFFINIS , is under the baton of their newly-appointed principal conductor Walter Weller. John Lill is the soloist in the Tchaikovsky Piano Concerto No 2, a refreshing alternative to the often-heard No 1. The concert opens with the Overture Manfred by Schumann. Introduced by CORMAC RIGBY.
