Dear Reader: In Stacey and the Bad Girls, Stacey and her friends get into big trouble when they go to a concert. I never went to a concert when I was Stacey's age. Instead, I went to my first concert when I was a junior in high school -- almost seventeen years old. I went to hear a local group called Bop Shoo Bop that played 1950s doo-wop music. This was the early 1970s, when the TV show Happy Days was popular. My friend Beth was old enough to drive, so she drove us and a group of friends. Our parents knew what we were doing, of course, and nothing like what happened to Stacey happened to us at the concert. We just wanted to enjoy the music and have a good time. And that's what we did. I've been to a number of concerts since
