A lot of my growing up had watching his shows on tv or even seeing him live on stage shows abroad with my father. His immense talent and endearing charm was timeless. And now Shane his son is one of our greatest breakout talents of Malayalam. Having done several films with him I got to see Abi ikka a lot of late. This is so sudden and so unexpected. My deepest condolences to the family. Our prayers and love to them always.
