Actor - director T Rajendher rendered his voice for his son Silambarasan for the popular song Yemmadi Aathadi in Vallavan set to tunes by Yuvan Shankar Raja. The song topped the charts and is a big hit among the youngsters.

Rajendher is over the moon for contributing his bit to his son’s venture.

Rajendher said, 'It was my contribution to my son's successful venture as director. Thankfully it paid off. The number has topped the charts and it is being repeatedly beamed in all music channels.'

Now to show his gratitude, Silambarasan has sung a song for his dad Vijaya T Rajendher for the movie Veerasami.

Veerasami features T Rajendher in the lead role with Mumtaj and Meghna Naidu playing the heroines.

Besides directing, T Rajendher has composed music for the movie. Silambarasan has rendered a peppy song for his dad in the movie.

A happy tit for tat, you can say.
