Tibetan dance in Playa San Juan

Hi there, I first visited Playa San Juan 4 years ago and have been coming back every year since, I love the place, such a lovely atmosphere. When we came in January a couple of years ago there was an evening dance event in the main square next to the church, I believe Tibetan dancing - I think this was the Dzamling Gar community based near Playa Paraiso - is this a regular occurence? I know the square is currently being worked on to provide I think an underground car park (please correct me if that's wrong), but I would love to see the dancing again. Also, are there any local classes that would accept a visitor for a few weeks? I shall be in PSJ for 4 weeks from the end of January and would love to join a class of some sort. Thanks in advance for any help / suggestions x
