Behind the players a storm brewed with dramatic flashes of lightning. Just before the end the lights went off briefly, but the music went on. Later most of the staff (plus a few participants) joined to play some excerpts from the Fireworks Music by Handel. Some played instruments for which they are not usually known - but the overall effect was impressive, energetic and lively.
Nature provided the fireworks with great jagged lightning slicing across the sky. Another brief power outage - but the musicians soldiered on.
