Definition of "panic"

How to panic: Put off brushing up long-booked Messiah until two weeks before the performance, since it's so well under the belt from previous performances.
Two weeks (or should that be "two eeks"?) before, find that your copy has been "borrowed". Spend spare time for two days going through all the possible locations. Twice. Including (just in case) the car boot. On an already overcrowded Saturday, text friend for name of music shop in Chichester (I could only remember the previous name), only to find he is taking part in a choral festival in St Paul's and not answering texts. Google for it and find it, ring them and "halleluia" they've got a copy in stock. Dash 20 miles each way, get to church to start throwing dots back under the fingers, to find that we're doing at least two arias I have never played before, one of which is in two seperate versions, one a fourth higher and which changes fingering significantly (also "colour" of piece. When I'm transposing, my ears change shape and my feet don't fit my shoes the same way).
Find that it all works somehow, and hope that you can play quietly under the choir parts so that the mistakes won't be heard.
Get a phone message asking for a recital programme you haven't worked out yet which should have been with the promoter about two weeks before - you haven't done the programme because you've been doing the above.
It's all good fun...
