Thought for the day: No matter how good a musician you are, if you're going to stand in front of an orchestra, you have to be able either to demonstrate or to anatomise what you want them to do. If you can't, you're in trouble. 

Anyway, Christophe Coin's cadenzas in the CPE Bach A minor cello concerto were fascinating yesterday. In rehearsal and in the concert, both were paragons of appropriateness, matched in mood, style and content to the piece itself: the concert one went off on a little crazy heavy metal guitar riff at one point and somehow found its way back. 'I thought we'd lost you for a minute there', I said as we left the stage. 'Whew', he gestured in his usual economical fashion.

I had excellent fish and chips before the gig in Perth, walking across the railway bridge over the river Tay (joined by a train at one point) as the blue and green light faded from the sky, with snow on the hills. It was freezing cold but it didn't matter. I'm hoping for a similarly memorable seaside fish supper experience in St Andrews tonight.
