M: Really'?
W: Yes. It's quite good fun. They teach you modern and traditional songs.
M: But, I'm not much of a singer.
W: Oh, come on. You should go. It's OK if you do not sing well. (24)It'd be a good way to practice your English.
M: (24)Yes. All right. Wait, what time does this singing thing finish? (25)I have an appointment with one of my professors at 8: 30.

M: Oh, that will be great. I can do both.
