A Puzzlement performed by Yul Brenner in the King And I. He was a smoking hot king, but that song fits not only the character very well, but I think most adults feel the same a few times through life. Yul’s staunch demeanor through the performance made it so memorable.
I Feel Pretty performed by Natalie Wood in West Side Story.
I like it because it is just so cheery.
Interesting coincidence, Rita Moreno was in both movies. She is amazing. I saw her on a talk show last year. She is still just spicy as ever.
