The music you hear (sorry, not on all devices) as you look at this page is Tuba Tune by C S Lang (Christ's Hospital Director of Music 1929-45), played on the trumpet by David Mason (1926-2011), David was a student of Lang's at Christ's Hospital and Professor of Trumpet at the Royal College of Music for 30 years. He was principal trumpet in the Royal Philharmonic Orchestra, but became known to a wider audience when he recorded the trumpet obbligato on the Beatles' track "Penny Lane". David was a member of the Christ's Hospital Lodge.
