Legnala Dana is certainly a popular Macedonian folk song. I’ve found 11 YouTubes of its performance in Macedonia, plus a few others of its being performed in Poland, Croatia, USA, etc. Here’s an old TV clip
Tanec, the Macedonian state dance troupe, made a recording, with added harmonies
In 1969 Atanas Kolarovski, former director of Tanec who defected to the USA, introduced to his North American followers a dance he called Legnala Dana, using the Tanec recording.
Notice how the dance phrases follow the record phrases exactly (after an un-necessary pause for the “right” starting point.) – not typical of 1st Generation folk dances – (where generic dances are applied to many songs, and where the song and dance phrases often don’t match.)
A search for Legnala Dana the dance yields lots of results for non-Macedonian recreational dance groups – all of whom would have learned from Atanas or his pupils. However I can find no one dancing to this song in Macedonia. There are 2 YouTubes of ‘live’ Macedonian singing performances with audience – normally a place where cameras like to pan to dancers every once in awhile to keep things interesting. In both cases people just sit.
Until I see evidence of a Macedonian dancing to Legnala Dana, I’m calling it a Macedonian song with 2nd G choreography.
