Very occasionally being a music librarian can take you to the most unexpected places. I've recently returned from a trip to Basel prompted by a production of a new ballet, Robin Hood , choreographed by British choreographer, Richard Wherlock , the Director and Chief Choreographer of Ballett Basel. So, what was the connection with my usual life in Cambridge University Library's Music Department? Music for the ballet was primarily by British composers, and included two, whose archives we hold here - William Alwyn and Sir Arthur Bliss . London in the 1960s, John Barry and Arthur Bliss, dartboards and the Kray Twins...I had to find out what it was about.
