Towards the end of "Dirty Dancing", at the final dance, Mr. Kellerman comes out on stage and begins to sing. Then he's joined by the staff dancers and some of the guests (Baby's sister, for one). Something about "hearts and hands".
For those of you of a certain age, in 1953's Titanic, the college kids and Audrey Dalton also sing the same tune, but with different lyrics, just before the ship hits the iceberg. So the tune itself must be older than both of those films (and presumably, older than 1963, when DD was set).
What is the name of that tune??
Just for trivia, Audrey Dalton's love interest was none other than Robert Wagner, who seems ageless. Over 20 years later, there he is again in The Towering Inferno and Hart to Hart.
