Leave him be. Was I the only one who got that he was joking around at the McFly blokes, pretending to treat them like naughty boys and shooing them off the stage? He was having a laugh, he wasn't upset, angry and or disturbed at all. He was joining in the fun. He was probably delighted to have a laugh at it all when it was so serious with the award giving and pats on backs which are so very often boring and predictable moments on television.
Bruce knows how to handle a stage and audience helping entertainment fun along. Why so serious about getting a younger (and maybe prettier chap?) compare in just because some have no understanding there's room for people of all ages broadcasting to the nation. Makes me wonder if some wouldn't like to see the death carousel for all humans at the age of 30 like the book/film Logan's Run.
What, I wonder, are the age ranges of viewers? Surely many enjoy the representation of age and his sense of comedy in Bruce? I'm not a pensioner, btw.
I don't think Bruce should step down and be replaced unless his bosses want him out, or he decides to stop working.
