I would love to have been able to sit and chat with Frank Zappa! He is my musical god and so much more!! I did meet his son Ahmet in LA around 2000, but it was just a "hi, nice to meet you" situation.
I have met some legends though, and even was allowed to spend some time with and ask questions of a few of them. Here is what I have off the top of my head. Met Prince twice, and twice he stopped to watch ME dance! Got to meet and get the autograph of Lou Reed and many people know, he was NOT public friendly! His bus driver convinced him he should come out and meet me after the show behind the theater ;~)) His bus driver also got me some ice off the bus for my tequila that I was drinking while I studied for my latin exam the next day (was there all afternoon hoping to get him to sign some pieces and say hi)! Got to spend an afternoon with Spencer Davis and he had some good stories he shared! I was luck enough to meet Ian Hunter and Mick Ronson and granted a seat on their tour bus for a 5 minute chat with each of them!!! They let two of us on the bus at a time and we each sat with one of them and talked, then traded places! Met Adrian Belew in LA once at a KC show. He came bursting out of a stairwell door and asked the bartender for a beer between sets. The bartender puts the beer on the bar and says "$10"! I said, "do you know who this is, he just got off the stage downstairs, he has played with Zappa, Talking Heads, Bowie and more, this is Adrian Belew". The bartender looks at me and then Adrian says "I have put out X solo albums as well" (I forget how many he said) to which I chimed in "Yes and 'Desire Caught By Tail' is my favorite". I then said "Hell, I will buy his beer if you are not going to give it to him" (he had no wallet or cash, he had just come from the stage). The bartender ultimately was convinced that he was with the band and let him walk away with his beer at no charge. I then asked Adrian to get me RF's autograph and he said no way! He did however autograph my Fillmore poster from a show by them a few nights prior! Jerry Harrison of the Talking Heads (got him to sign my shoe, same with Gilbert Gottfried), Sammy Llanas of the Bodeans, Brian Ritchie of the Violent Femmes is close friends and used to be room mates with my uncle, so I have met him on a few occasions. I worked a Rolling Stones concert once and they were only about 10 feet away at many times that day, but I was not allowed to talk with them! Met Bill Kreutzman of the Grateful Dead!!! Been to Todd and Michelle Rundgrens house years ago when Michelle was hosting a local play. My girlfriend is a belly dancer and she danced at their wedding a couple of decades ago! I have had the opportunity to approach Carlos Santana on a few occassions but never have because a friend who is a pilot explained to me that Carlos does not like being approached by the public. This was based on his interaction with him (pilot friend) having encountered Carlos on a flight and Carlos just stared straight ahead as he thanked him for being on board, his wife spoke up and said he was very shy (or maybe it was a flashback to that Woodstock state of mind)!!! Mike Gordon from Phish, Greg Koch, Michael Franti and others that are not coming to mind at this time ;~))
