I've often wondered what would happen if Abbott and Costello hijacked a concert review.

I'm guessing it would unfold something like this:

Abbott: Dude, Who played at the Delta Center on Monday night. Costello: I don't know. Who? Abbott: Yes. Costello: Sweet! Did they have the classic lineup with Rick Wakeman and Steve Howe? Abbott: No, that's Yes. Costello: So what is it … Yes or no? Abbott: It's neither. I already said Who. Costello: When? Abbott: Just now. Costello: Who?

Abbott: Yes. Costello: That's what I thought. Abbott: You thought Who? Costello: Yes. Abbott: No, Who. Weren't you listening? Costello: Yes. Abbott: No! Who! Costello: Who played what? Abbott: A mix of old hits and new songs over the span of nearly two hours. Costello: Did they play "Roundabout"? Abbott: No, that's Yes. Costello: I know. Make up your mind. Abbott: About what? Costello: About who you saw in concert. Abbott: Who! Costello: You tell me! Abbott: I already did!

See THE WHO, B6
