''Yesterday'' in Concert!
Last night, the Swidish rock band, Yesterday, gave a concert in Kunming.
More than five thousand people were there. Most of them were students or young people. They enjoyed the music very much.
In the middle of the concert, one of the singers, Max, had an accident. He jumped up and down, but he was very careless. He fell down and broke his leg. Some people took him to hospital.
After Max left, there were only two singers-Erik and Elsa. They didn't want to stop the concert, so they went on.
They sang some of their most famous songs:" Why did you leave me?"," There was someone in my heart", "She didn't remember my name", and "I can't forget the past".
At the end of the concert, Erik sang a song in Chinese. He sang very well.
After the concert, he said:" I'm trying to learn Chinese, and I like listening to Chinese songs. I learn that song when I was in Shanghai last month."
