Wow - sounds like a great night - so awesome they pulled you up AND that you had your guitar with you. Never thought of the lefty thing! You are an amazing performer MAB, I'm sure everyone was blown away. We all need to keep practicing and preparing for those moments for sure. I honestly think I walk away from my guitar a little better, every time I play it. Even if it's just ten minutes, sometimes that's all you have - it makes a difference.
You are always ready MAB, and that seems to separate the pros from the rookies. There's a big lesson in that. What I'm learning is there really isn't any time for being shy in the business. There's always going to be someone out there - might not even be as good as you, who is ready for the opportunity and not shy at all. They are going to succeed over someone who doesn't know how to play, or who is shy, or just unprepared. Still working on all of those things 
Justin - Hope Kenna's show was good last night. Great that you are able to get out and support her. Sounds like you have a crazy schedule. I missed the posts where you might have mentioned this, but where you are working now?
PS - Taylor Swift is awesome. She is constantly reinventing herself and is and incredible talent. I hear so much Taylor bashing, it drives me crazy. I really think jealousy is at the root of all of it, it's just so ugly. For some reason it's just so difficult for people to be genuinely happy for one another. She deserves to be where she is today, there's no question.
