I met Mike Smith outside the BBC in 1986 and found him completely rude and off hand. OTOH I saw Jimmy Young a few minutes later and he was a gentleman.
Also did anyone meet the infamous Jimmy Savile?I can remember the secretary of my local hospital radio meeting him and he said he found him creepy and false.
I had the misfortune to appear in a TV ad with the odious Jimmy Savile. I never saw the ad for Green Shield Stamps but luckily my encounter with him was brief - he kept on calling me 'superstar'.
