I was a Custom Shirt Manufacturer in Beverly Hills, CA and made several business acquaintances with so called "high profile" personalities while conducting business during the early 60's through to the early 1980's. Here's the list of people whose character impressed me the most, in no implied order.

Roy Rogers and Dale Evans
Dean Martin
Frank Sinatra
Marty Robbins
President LB Johnson (during his Presidency) .........
..... the president was referred to me by his good friend Wesley West, a wealthy oilman client from Houston.
John Wayne
Elvis Presley
Lee Van Cleef
Gene Hackman
Mamie Van Doren
Robert De Niro
Dan Blocker
Michael Landon
Steve Martin and Burl Ives ...............
..... it happened that I bought a house on the same street (Romero Canyon Rd) as these two entertainers after selling the business and moving further north to Montecito/Santa Barbara, CA. They were both regular guys.

There's probably a few others, but while not being particularly "star struck", these were the most amicable and memorable of the bunch.
