Problem: Given the question: M: Funny you should say that because, er, a similar thing happened to me one time when I was abroad. We were actually doing a concert in this bar in Germany. W: Really? M: I was actually about to appear on stage, you know, with the band, and I just thought, "I'll just go out for a little walk and get some fresh air," 'cause I had about half an hour before we had to go on. W: Uh-huh. M: And I went outside,you know,had a look around, walked around for a bit... and then I decided to go back and, uh, I couldn't find it! It was about two minutes before we were supposed to start. W: No, you're joking! M: Yeah! I thought, "Ah! What am I gonna do?" W: Could you ask for directions? M: Well, I tried. I asked an old woman, but she didn't speak English, and I don't speak German... W: Don't you? Oh, right. M: And then, I realized I couldn't remember the name of the bar, or the street it was on or anything. So, you know, I was in the middle of a town I didn't know, not knowing the language... and luckily, I saw someone wearing one of our T-shirts. He was obviously going to the conceit, so I sort of followed him back to the bar. W: Wow, that was lucky! Thank goodness! M: And when I got there, the guys were like, "Where have you been? We thought you'd run out on us!" Anyway, we managed. What was said before this conversation?
