When I thought about posting on Valentine's Day, I just kept thinking of this scene from Holiday Inn (1942). Here is Bing Crosby singing "Be Careful, It's My Heart" while Fred Astaire dances with Bing's girl. It's a sad/sweet song. Bing's voice delightful. The dancing is wonderful. But I think my favorite part is the snow coming down outside the windows and the two dancers posed in silhouette behind the paper heart.
