I still remember my first gig. December 7, 1977 at the Howard AFB Youth Center. The band had been together for 6 weeks and that was the extent of my experience on the Bass Guitar. We were built up until the day of the show and there probably were 100 kids in the center. During the first song about half of them left!
I had some cheat sheets with written notes on them and started playing the wrong song during one song. My hands were shaking so bad I could barely fret a note. It took a good 3 years for me to get over my stage fright. I used to drink heavily to help combat it. (I'd been drinking since age 15) Lucky for me I was burnt out on drinking by age 20.
I guess my point is, we've all been where this kid is, just not stupid enough to post a video of it.
