Repeated Blunders in Mega Audio Functions

As usually, there was a lot of hulchul and noise from mega fans who wished Power Star Pawan Kalyan's presence at the audio launch of Stylish Star Allu Arjun's  'Iddarammayilatho' audio launch. They interrupted the speeches of many guests who attended the audio function. Even Puri Jagannadh was also interrupted highly by the fans. In that sense, the function could be said a partial success. Who are to be blamed these kind of repeated blunders in mega audio functions? 

Many analysts feel that the makers of the movie should have announced the guest's name officially prior to ten days to the audio launch of the movie so that mega fans could understand that it is unnecessary to make protests on the presence of Pawan Kalyan at the venue of the audio launch and there could be a smooth go of the audio function. While issuing entry passes also the makers must educate the fans at their best. Hope, hereafter, the makers of the mega movies would be very cautious in mega events, more particularly on the prior announcements of the guests of the  functions in TV channels, newspapers and web media.
