I've done some googleing, and found a ref to a song I should have known about, but didn't. The following is from
A Class Act, music and lyrics by Edward Kleban. It is, appropriately, titled "Charm Song."
LEHMAN
Now kiddies, a Charm Song is the southern belle of musicals - it don't have to do a lick of work - it just has to make the audience smile.
CHARM SONG
NOTHIN' TO IT
CHARM SONG
YOU CAN DO IT
TAKE A LESSON FROM THE KID
YOU'LL BE GLAD YOU DID
CHARM SONG
BLITHE AND BREEZY
CHARM SONG
IT'S SO EASY
IF YOU WANT TO GET AHEAD
IT'S THE WAY TO KNOCK 'EM DEAD
THEY DON'T REALLY HAVTA LAUGH OUT LOUD
DO THAT CHARM SONG AND TOMORROW AT TEN
THERE'LL BE A CROWD
FOR THAT
CHARM SONG
SELL THOSE TICKETS
CHARM SONG
STICKY WICKETS
MELT AWAY
I SWEAR IT DO NO HARM
TO TURN THEIR HEADS
TURN ON THE CHARM!
Class, how would you write a Charm Song for a musical about Fred Astaire?
MONA
Gingerly!
ED
How would you write a Charm Song for a musical about the Flying Wallendas?
LEHMAN
I'd try it in swing time.
YOU'RE IN BOSTON WITH A SLOW ACT ONE
CUT THAT BALLAD AND THE SHOW WILL RUN
ON SIMPLY
CHARM SONGS
SHORT AND SNAPPY
CHARM SONGS
KEEP 'EM HAPPY
SHOT THAT SMILE
I SWEAR YOU CAN'T GO WRONG
SO LIVE AND LEARN
DO A GOOD TURN
IT ALWAYS GOES
IT SAVES MOST SHOWS
ED
IT DO, IT DO!
LEHMAN
AND WHEN THEY HEAD
FOR SARDI'S
WHISTLING RIGHT ALONG
THEY'LL TURN AND SAY
"WHAT WAS THAT CHAR...MING...
SONG?"
I wouldn't kid ya!
