varuna varuna from Balaraju 1948

Quite a few of the songs were uploaded recently including the more popular 'o balaja jaali leda' https://www.youtube.com/watch?v=F5k4mGgPaew, Yevarine nenevarine' https://www.youtube.com/watch?v=oIhD99JVhu0, 'raja rara' https://www.youtube.com/watch?v=6zexya1lbIM all by S.Varalakshmi. There is also a sort of folk tune
