Chris: Hi! Did you have a good
weekend? Terry: Yes, it was great. Lilly: What did you do? Terry: John and I went to a rock concert on Saturday. It was at the Central Stadium. Chris: Who performed the concert? John: Okean Elzy, my favourite group.
Terry: It was only three o'clock in
the afternoon when we got there, so we watched as they were setting up the speakers for the sound system. One of the men working there even asked me to help, so we ran over and gave him a hand.
Lilly: When did they start the concert?
John: At six o'clock, and since we had helped earlier we were allowed to sit at the edge of the stage. We were almost close enough to touch the performers.
Terry: The best moment of the concert for me was when Svyatoslav Vakarchuk and his team appeared. I couldn't believe it when he walked out. I felt very excited to be so close to my favourite singer.
Chris: Did you speak to him?
John: Well, there were too many people. Everyone clapped. Svyatoslav stopped right in front of us, leaned over and told us to enjoy the show.
Lilly: What happened then? Terry: He started singing all of his hits. We all joined him and danced to the music. The rest of the concert was wonderful, and everybody had a great time. Chris: How did you feel after the
concert? John: As for me, I was happy because I had had the chance to see my favourite band and talk to Svyatoslav in front of five thousand people. Lilly: And what about you, Terry?
Terry: I felt exhausted, but also delighted. I enjoyed the concert very much.
Chris: I see you've really spent a great time at the weekend. John: Yes, we've been lucky.
Lilly: Now I've got an idea as for the theme of the next issue. Terry: We'll speak about music and favourite singers, won't we?
