New Kids On the Block. I was 10, and it was for a friend's birthday. She got to invite 2 people to go, and I was one of them.
I've been to lots of concerts, but most of them were country artists (REAL country.....George Strait, Garth Brooks, Reba, Tim McGraw, Faith Hill, Toby Keith, Travis Tritt, Vince Gill, Brooks & Dunn, and some others). I've also seen Aerosmith.
