Arjay,
As I write two KTV long plays come to my mind and I am sure they will ring up you too.
If I remember,Karachi received a torrential downpour in 1978 causing widespread damage to city life.This led KTV to produce a long play "Baarish" sometime in Sep 1978. Liaqat Durrani Sahib(Marhoom)played a memorable character. It is such a pity these plays have never been repeated and today's TV generation mostly attuned to ufone and Jazz produced commercial stuff don't know what quality TV was in the 70s and 80s.
I didn't see it--but I did hear a whole lot more about it from my colleagues at PTV. They say it was also recorded at places where BAARISH made worst for dwellers...
INDEED HE DID...and that I knew Liaqat Bhai from Khuda Ki basti days that he played a small but mazaydaar role as my silent boss with no dialogues... he was a jovial person full of wisecracks like Qazi Wajid....
