This is something he seems to have inherited from his father. Sivakumar has been known to have a very strong and sharp memory, especially with the way he recited the whole Kamban En Kadhalan on stage once. Even Suriya has exhibited the same trait. Remember the scene in Poovellam Kettupar where he say the name of 108 flowers non-stop. He has repeated the feat once on stage much to the amazement of everyone present. Its not just good looks and physique that make a star!
