One of the perks of doing what we do in radio is occasionally you get to meet famous people. Usually it's at what is known as a "meet & greet" where you're herded ushered backstage, usually before the concert, and the famous person comes in to meet and greet you.
If you're lucky you get to take a photo with your hero. Maybe make a little small talk.
It usually lasts about five minutes.
Sometimes the famous persop will be really down to Earth and will spend ten or fifteen minutes making each and every fan there feel like he or she is the most important person in the famous person's life. George Thorogood is one such famous person.
Sometimes the famous person is a dick shy and you only get about a minute with them.
The best thing to do when meeting a famous person is don't be a dick as well be yourself.
Think about it - YOUR party is their JOB.
If your plans for the evening involve getting totally effed up having a couple of beers, do it AFTER the meet & greet. That fifth of Jack Daniels you see your hero chugging backstage and onstage is more than likely filled with raspberry Snapple. Show up backstage smashed and you're about as welcome as, well, if someone showed up smashed at your work.
If you have something you'd like your rock hero to sign, make sure that it's not something that will obviously be offered up on ebay before the end of the first encore.
And when it's time to take the photo, don't molest touch the artist unless they touch you first. Some of these folk are world class germ-a-phobes. If the artist puts his arm around your shoulder for the photo, a discretely placed hand on the midback is fine.
Good luck, and I hope you get to meet your rock & roll idol.
