Problem: M: Oh, thanks, but I am not in the band any more. In fact I'm not in the group at all right now. W: That's too bad. You're such an amateur musician. Why did you leave the group? M: I just couldn't be a full-time student and still practice with the band every night. I also missed a couple of performances during my midterm exams. And I thought I'd better quit before the band leader fired me. W: Hey, you know my friend Charlie, don't you? He plays the piano. He and some of his friends are getting a band together. And they need a good singer. M: I wouldn't have time for that either. W: Oh, I don't think they'll practise very often. Charlie and his friends are all students, too. I'll give you his number and you can get in touch with him. What was said before this conversation?
