The format of putting a performer in front of an invited audience
largely consisting of his or her showbiz peers and buddies makes me cringe. I think it relates to the notion of exclusivity, and privilege (being invited to the performance) being afforded to those who have a surfeit of it already.
I also baulk at seeing outrageously well paid sports people earning yet more money by endorsing products in commercials. I don't blame them for doing it - I would too - but it all seems rather excessive and greedy.
