George and Ira Gershwin’s “Love is Here To Stay” was first written for a movie, but is remembered as one of the many wonderful songs in the rather silly “An American in Paris,” a movie starring Gene Kelly and directed by Vincent Minnelli. (The score is all Gershwin.) Oscar Levant has a scene-stealing role as pianist buddy of Gene Kelly.
Of course, the tune is marvelous. But I think the words are great, particularly that last verse, “In time the Rockies may crumble/Gibraltar may tumble/They’re only made of clay/But our love is here to stay.”
Here is Blossom Dearie’s performance, one of many worth exploring on YouTube or elsewhere.
