This was the song taught to me by my Aunt, Ratna Atte (Father’s Sister) when I was in 10th grade. I have been singing this ever since, and everyone in our family do so when we do Seva for Shri Raghavendra Swamy. Here are the lyrics for Raya Baro Thande Thayi Baro lyrics in Kannada. I will post the lyrics in English as soon as I get time to translate the same.
