We had our Song and Dance celebration last weekend. Its old tradition in Estonia, first celebration was held on 1869 in Tartu. Something very unique and emotional. I´ve been participant once and guest almost every time :).
The same tradition is also known in Latvia but their festival is a bit younger than ours. Let me share one beautiful song from Latvian celebration as well. Actually this song should be Livonian by origin and it has also Estonian words, I learn it at primary school.
