That is just brilliant! I love these festivals that seem to take place all over Europe. We very rarely have them in the UK. I'd love to know the significance of those prison outfits! And that recycling bin man! Bizarre. And Smurfs too! Lol.
A few years ago I went to Spain with my mum. We stayed in a small northern Basque town. One evening I wandered into the town centre, and there was a Basque festival taking place, with young people doing traditional Basque dances in costume on a stage. It was fantastic to watch it, and it wasn't staged as a big tourist display - it was mostly local people watching. We should definitely have more things like this in Scotland.
