Or something along those lines. Being cynical, an excuse for some traditional music and dance groups to get together, play some music and have a dance. There must have been more than 10 different groups of musicians and dancers, one or two only musicians, one mainly musicians with a couple of dancers and the majority where the dance and music were both important. Some groups of younger musicians and dancers maintaining the traditional styles.
No publicity, no tickets. It was organised, each group getting an award after its performance, but mainly music and dance groups performing and public watching and enjoying it all.
Whatever the occasion and reason it was facinating to watch.
