not sure how i felt about it, i have to say i do feel sorry for th eolder two, as mentioned they had seen the other side of him and knew him before his major issues that he is currently going through. i think it is quite clear that they (mason especially) were cleasrly cut up by his state and did care about him an awful lot.
his younger son probably only remembers the shite so has never had him as any sort of authority figure.
again, i dont see why they had to do it on tv, but gazza was initially up for it according to the show last night.
