My first wife worked in the Columbia office of Senator Strom Thurmond for a few years and once in awhile one of his kids would come to the office and play on her typewriter. That's really nothing, but...
As a perk of her working there, she and I got to go to the premiere of The Great Santini and met and talked with Robert Duvall afterwards. Very personable and accessible guy.
Casual encounter; my bud Brian and I were walking out the back gate of the paddock while at an IMSA GTP race weekend at Charlotte Motor Speedway in the mid 80's and Al Holbert, Jr. was coming in the gate. We just did the acknowledgement nod with a "hello" and he returned the same.
Because of being on a listserv of Creedence fans, our whole family was treated to tickets for a Creedence Clearwater Revisited concert and aftershow passes at Chastain Park in Atlanta in '97, so we got to meet Doug Clifford and Stu Cook, the original Creedence rhythm section. Oh yeah, it drizzled during most of the concert, so the rain songs were especially fun. Elliot Easton (ex Cars guitarist) was lead guitarist for them at that time, but he didn't come to the aftershow thing. I got to meet him later when I went to one of their concerts in Peachtree City. He was not a very chatty guy, but you should hear some of his work while he was with them.
Also because of being on that listserv, my oldest son and I got in for afternoon soundcheck and were able to meet John Fogerty afterwards at an indoor venue in Charlotte a year or two later. We went to the concert that night, but John C. Fogerty doesn't give away concert tickets to commoners.
Again, with the CCR fan listserv, both my sons and I were guests of Creedence Revisted for the pre- and post-race concerts and IRL race in Charlotte in '99 when that crash debris went up in the stands and killed three people. Tragic and scary... it happened several hundred yards from us. The race was black flagged and the post-race concert cancelled.
My current wife taught John Mellencamp's daughter Justice in middle school in Hilton Head when she lived there in the late 90's.
