The late Danny Kaye was supposed to be a rather horrible individual.
Geoff Hurst is another I've heard of as being a tosser. There are many tales out there of Geoff & Danny.
No Danny Kaye was not horrid.
Going back many many years,my dad had a job washing up dishes in a resturant in London and Danny had a meal there and wanted to met the staff behind the scenes he tipped all staff my dad who washed up etc etc
Danny told them it is not fair that people who work just as hard as the waiters in the resturant do not get tips
