Only trouble is, that I'm going to have to fork out between nine and eighteen pounds to get hold of something that lasts about ten minutes! Which isn't really good value to me...

Ah, but how many times are you going to play it? :)

Of course, my problem is that I keep spending money on different recordings of my favourites. I realized I passed "Rational" quite a while back when I tried to work out how many Mozart Piano Concerto cycles I own and I had to count three times to get it right.
