There are tillAnAs by Chitravina Ravikiran, S.Rajeshvari and V.Subramaniam but I don't have the lyrics for these.
I tried to match the words you have given with the texts of some 350 odd tillAnAs that I have but without success.
Do you have a recording of this and is the audio available somewhere on the net?
Any other information would help to locate the lyrics.
I have managed to get the two clips i have from the song onto a file. I will email you the files but you might have to add me to your contacts list since hotmail will send me to you junk folder.
More than the lyrics, I'm looking for a cd or tape from the artist itself that i may purchase. plus the meaning of the caranam.
