On Sunday 7 May in a year prior to 1997, at 7:30 in the evening, Emanuel Hurwitz, a violinist, and his wife, Kay, a violist, gave a performance of Mozart's Sinfonia Concertanti at St. Mary's Church Hall. The couple were accompanied by the Dollis Chamber Ensemble for the first time ever. Hermione Granger had a poster for this concert stuck up on the bulletin board in her bedroom in the Granger family's house.
