Take a lesson. Learn it.
From the guitarist at the YouTube link: “I don’t often see this, but when it happens it’s always 99% kids that are doing it. Before they become jaded (age 8), they still have that spontaneous spark, that reaction to music that we all used to have. Emotion is no.1 priority and they express it without shame. If I could hire kids for my shows, legally, I would do it. Imagine being surrounded by these mini-tornadoes during every song. It’s the ONE thing that gets people to pay attention. “Awww, isn’t that cute!” the adults say, smiling at each other.”
