"Wee Willie Winkie"
When Shirley Temple is singing to a mortally wounded Victor McLaughlin.
I don’t think I have ever cried from watching a movie but a few have made my eyes a little misty.
Interestingly, you mentioned the only one I can recall off hand. Wee Willie Winky, where Shirley Temple is singling “Auld lang Syne” at Sgt, McDuff’s funeral.
