Harshu Harshu yen idhayam parithaval needhan yendrum
Yellam yennakai adhu needhan boo

Harshu Harshu vizhi ora paarvaiyil siraithai in you
5 years kadandhaachu its your birthday too

Thavithu irundhidum naan pizhaithida varamai pirandhaval
Anu anu vai yennul paravida thudika

Harshu you Harshu are incredible Harshu
Why Harshu my Harshu happy birthday to you

Thaanda kodu nee pota
Vinnai thaandi varuven romba bright ah
Andha moon-u ku tough ah azhagula veluthu vaangura ma

Padacha avanumey thedum
Perfection definition neeyum
Adada konjam konjama yennaku sondhama
Sendhu mayakura ma

Adi raasathi yen ulage nee yena varthai kulla adaka mudiyuma
Thaen pola kavidhaiyum thevaiyum illa penne nee pesu ma
Oor raavil motha vazhkaiyum nee maathida
Mela irundhu vidhi ezhudhiyadhaam
Kooda sendhu kadasi varaiyum kadandhida kai korthu sera vaa

Harshu Harshu Harshu Harshu
Yen idhayam parithaval needhan yendrum
Yellam yennakai adhu needhan boo

Harshu Harshu Harshu Harshu
Vizhi ora paarvaiyil siraithai in you
5 years kadandhaachu its your birthday too

Thavithu irundhidum naan pizhaithida varamai pirandhaval
Anu anu vai yennul paravida thudika

Harshu you Harshu are incredible Harshu
Why Harshu my Harshu happy birthday to you baby boo
