He always sounds so bitter in interviews, like he hasn't had the due respect he thinks he deserves. As far as I'm concerned, he has definitely made the most of the little talent he had. He was an ok singer, an ok dancer, an ok comedian, an old fashioned all round entertainer, but he never had an outstanding talent.
He was a very good presenter in his day though, he was brilliant at panel shows and interacting naturally with the public, but those days are long gone.
