We are traveling to Wales in late May for a two-week trip. After a few days in Cardiff, we will head to the St. David's area and then to Conwy.
We'd love to see a men's voices choir. The Visit Wales website has a helpful list of choirs. I'm keeping an eye out for concerts. But some of the choirs list their practice time. Can I drop in on a practice? Should I email first? I assume that some sort of contribution would be appropriate? Any guidance on the protocols would be appreciated!
