Lots of people from politicians through work to the Royal Family (Charles few times through his Trust/Di/Queen Mum 6 or 7 times, and some of the others). Met some sportsmen such as Gary Lineker, Tom Watson and Greg Norman all very nice and sane, some from the music world as I used to book bands at Uni - along with the likes of Eartha Kitt through family friends (she was dreadful and she had a stuck-up daughter slightly younger than me at the time.
One of the most fascinating was the lawyer who defended OJ Simpson, Johnny Cochrane, the man who came out with "If the glove doesn't fit, you must acquit" - he has been dead some seven years now.
Dated the daughter of someone famous too, one of Thatcher's ministers daughters and had the Secret Service checking me out.....my bank manager tipped me off.
