The swinging sounds of the Hot Jazz Band warming us against a night bracingly clear and cold, while beneath us 800 fit young people engaged in (non-alcohol fuelled) energetic and explosive fun and celebration, the lovely, well-dressed dance partner on my arm and I danced on the roof of the boat a smooth calm Charleston as the spectacular spotlit hills and monuments of Budapest glid gracefully by. I’m still smiling.
