GSJ 17th Concert SEGA Special has ended safely. This time, I had unplanned appearance on stage and during encore, I played even the air guitar in front of the orchestra suddenly, and the orchestra was also wonderful, so I enjoyed myself very much, too. I am not sure if I was a little disrespectful. (^_^;) I wonder if all of you were able to enjoy it.
