IPCA Laboratories the name ... now left it .. but still within it not in management .." Meanwhile, Amitabh Bachchan is not too pleased with the reports which suggested that he is using his twitter account to promote Abhishek Bachchan's Players. Big B wrote on his blog: "And yes ... I do retweet the good reactions of praise for Abhishek's films .. and yes I am his Father and shall not stop from doing it just because a few abusive elements on this social network think otherwise. Look into your own 'daman' and see how every single tweet of the media is all about themselves and a request to go watch their particular programmes. No one ever complains about them do they ??Hey For regular updates on the latest happenings in Bollywood kindly subscribe www.youtube.com/thebollywoodshow
