The Royal Scottish National Orchestra's Glasgow concert tonight has had to be cancelled because of what my Scots godson, in far less extreme conditions down in the Borders, once described as "horrifying wind and rain". The programme? The Suite from Rimsky-Korsakov's The Snow Maiden, about a northern people in the grip of extended bad winter weather until the icy heroine should be melted by the rays of love, and the second act of Tchaikovsky's The Nutcracker, where admittedly it's in the first that ballerina snowflakes eventually get tossed around in a storm and the heroine heads off with her Nutcracker Prince to the indoor warmth of Sweetieland. The RSNO expects tomorrow's Edinburgh concert of the same programme to go ahead as planned and is offering full refunds.
