Uyire oru varthai sollada song lyrics uyire oru varthai sollada
unnakaga kathuirupen ennai nee etrukolada
unnodu naan irupen ..

unnai piriyumm nimidum methu
unmel irukum aasai methu

anbey anbey ithu nijam thana sollu

sagiey sagiey ennai kollamal kollathadi

uyire oru varthai sollada
unnakaga kathuirupen ennai nee etrukolada
unnodu naan irupen ..

oru naal unnai parthu parthu enn kangal verkuthada..
maru naal unnai parka mudiyamal ullam vaduthada..

ini endru endru neethaan !! en nilal kuda neethan ..
kaan parkum thesai ellam adi  neethana engum ..

ullam engi engi manum kaneeril mulguthada anbe ..
unnodu valazha enn jeevan enguthada..

uyire oru varthai sollava ennakaga neeirupa
unnai naan etrukollava, unnai indri veeru illai..

Arugil nee vendum endru enn ithaiyum ketkuthadi..
Kanavil Naan Kanda Kavavu indru Nijamaai Maariyatha Di....

unnmai kathal ellam poiyaai aanathu illai
aanal enthan kathal uyir vaalum varayil

theedatha panth…
