We were playing at a wedding reception in a tent, and the lights in one corner of the buffet failed, so Derek who plays the mandolin wandered in there, since there wasn't any kind of crowd, and he tucked in. He drifted out reporting that they had some funny fishpaste, but it wasn't bad stuff at that, if you washed it down with beer. Which turned out to be the caviar. Since it's fishpaste after all, you spread it on crackers or toast. I'd sooner have Marmite myself.
