Children’s Yolka (Matinee) at St. Nicholas Russian Orthodox church in Dallas/McKinney, TX. Two sisters, Natalka and little Olenka, are singing a Ukrainian ‘koliadka’ (Christmas carol).
This is a song about the "Three Holidays" – Nativity, St Basil’s day and Theophany.
The children were asked to "perform something" in order to get a gift from the Magus.
Many more Yolka and other church videos are available from multiple sources, courtesy of Natalia:
