From THE SOUND OF MUSIC (1965)

[MARIA]
Perhaps I had a wicked childhood
Perhaps I had a miserable youth
But somewhere in my wicked miserable past
There must have been a moment of truth


For here you are standing there, loving me
Whether or not you should
So somewhere in my youth or childhood
I must have done something good


Nothing comes from nothing
Nothing ever could
So somewhere in my youth or childhood
I must have done something good

[THE CAPTAIN]
Nothing comes from nothing
Nothing ever could

[MARIA]
So somewhere in my youth or childhood
I must have done something good

[MARIA AND THE CAPTAIN]
Nothing comes from nothing
Nothing ever could
[MARIA]                  [THE CAPTAIN]
So somewhere in my youth or childhood
[MARIA]                     [BOTH]
I must have done something, something good
