And in the key role of Charley, Mr. McClure scampers to and fro with tireless energy, flouncing in and out of his skirts with comic verve, employing a funny, pinched falsetto when Charley is impersonating his aunt. The most famous song in Loesser’s score — really the only famous one — is “Once in Love With Amy,” credited with saving the musical’s fortunes during an uneasy out-of-town tryout, when Bolger invited the audience to sing along.
As performed (and led) by Mr. McClure, a nimble dancer and terrific singer, it naturally brings the show to a genial, mildly intoxicating climax. Normally I find the invitation to sing along about as appealing as a date with the dental surgeon. On this rare occasion, I found it almost impossible to resist.
This doesn't quite top Frank Rich's now-legendary 1987 leap onto the stage of "Starlight Express" in roller skates, but we're still impressed.
