The ambiguity I have is ORT/OUT which could go in either position where the checked letters give O-T. But no further forward alas. Still, I was concentrating last night on the BBC Young Musicians where I heard the second (of at least a dozen) most shattering performance of the Shostakovich Cello Concerto #1, by a 17-year-old. Such musicianship is astonishing in a teenager. (The best was the TV performance by Slava in the early 1960s.)
