I mentioned the musical Mame here the other day. Here from a BBC concert of Broadway music is that killer title song as performed by a superb orchestra and chorus under the baton of John Wilson, who was obviously the winner of a Stephen Colbert look-alike contest. The performer near the end who looks a lot like Seth MacFarlane is Seth MacFarlane.
One point of amusement. Everyone in the chorus is reading from pages with the lyrics on them except for one guy who has a brief solo. And of course, the one guy who doesn't have the lyrics in front of him gets the words wrong…
