听力原文：W: Robert, you play the guitar, don't you？
M: I used to. But I haven't played quite some time. I don't really have time these days with all my studies. Why do you ask？
W: I'm trying to organize a group to play at some parties on weekends. We still need a guitar player.
M: Well, I don't know. But your idea sounds fun to me.
W: Oh, it will be. I'm more or less in charge of things, so if you want to give it a try, you're in. It's as easy as that. Besides, it's a great chance to get out and meet people.
M: But I haven't practiced for a long time. I don't know if I remember any songs I used to play.
W: Don't worry about that. I just thought I'd ask you to try and join us sometime when we were practicing. We'll be practicing for a few months before we give performances.
M: OK, I'll have a try.
W: I'm sure you can do it. And it will be fun, too.
