Hi Fido,
What a fascinating (and envious) lifestyle you've led!
Mine only comes close by way of working for Sir Ralph Halpern who owned a chain of stores in the UK called Top Shop & Top Man.... I worked for him whenever there was a Miss World Competition as they sponsored it way back then.... Used to meet each of the winners for six years, chatting and drinking with them, then taking official photos for promotional material and then the Public store appearances which were also taken by myself. That was a most enjoyable period for me!
