Paul: *him* who.

If the group is more than a dozen or so, strict rotation may be the easiest way to share the responsibility, applause, & blame (supposing, always, that it is permitted to pass or to make a request). But short of that, it is more pleasant IMO if one may go out of order to bring up a related song (as in parliamentary questions: arising out of that reply) -- supposing, always, that participants are on the alert for nonparticipants, and eventually make requests of them.
