Haha The taste of PP! I think the same. Although seeing as it's a progressive festival, I think there should be progressive food for sale. Perhaps a musical sausage, or a burger in the shape of a mellotron...
The taste of PP for me is Chinese food and hamburgers. This reminds me to exchange some Swiss Francs for Euros so I can buy hamburgers outside the venue. I've decided that 2 per day is the legal minimum. Better still if they have lots of unhealthy stuff to put on them
