"Look what I've found"

How I remember seeing Ethel Merman in a revival of 'Annie Get Your Gun'! She must have been in her sixties then, belting out the Irving Berlin tunes that he wrote specifically for her to sing. 

During intermission we sneaked into an empty box overlooking the stage for the second act. During the curtain calls, I shouted, "Sing out, Louise!" and she looked up and waved at me.

This particular song from the show always was special for me and I never quite knew why. Then recently, I found Jonathan Groff singing it as a kind of gay anthem and then I suddenly knew why.
 
It's just under two minutes. Utter perfection as a song.
