What's the tambourine dance?

Question

Apparently this is traditional at weddings for my future son-in-law's family, but I've never heard of it, and can't find it online.

Any input would be appreciated.

FYI, he's from California, with family in Michigan. Ancestral heritage is primarily Irish.

Answer 1

There's Greek, Chinese, Morracan, Islam.....
