I met Roy Clark in the early 90's when I was working at the Bloomington, IN airport while in college. He was just super friendly. Great guy. Gave me a $100 tip for carrying his luggage from the plane to his bus. I tried to refuse it but he insisted. He told a few stories and was humble as could be. I told him I grew up watching Hee Haww with my Dad.
Of course this thread has to include Glen Campbell.
