Sam: I'm going to tell you what we're going to be doing this weekend. We're taking the concord to London for a party at Alec Guinness' place.
Frasier: I'm not so sure that... Sir Alec Guinness?
Sam: Yes, well, I know it's a long way to go. But Stephen is going to be there, he's promised to play some songs for the new one.
Frasier: Look, I don't know... Stephen Sondheim?
Sam: Yes. Oh, and you'll never guess who'll be singing with him.
Frasier: No, please don't tell me, please.
