《A spoonful of sugar》是《Mary Poppins》系列電影的插曲，由Morgan Evans、Bob Rivers作詞、作曲。其完整歌詞如下：
Well you can cry
Your face down on the counter crying
A spoonful of sugar sure helps that churning in your belly
And you can laugh
Your face up in the air laughing
A spoonful of sugar sure helps that feeling in your belly
And you can run
Your feet down in the gutter running
A spoonful of sugar sure helps that feeling in your belly
Oh Mary Poppins, with a spoonful of sugar
Oh Mary Poppins, you can take a boil and make it cool
Oh Mary Poppins, with a spoonful of sugar
You'll do it for a smile and then you'll make it go away
So we cry, we laugh, we run and laugh again
It's alright with me if we go up in smoke
Because you're sweet to me and I am happy just to have met you
With a spoonful of sugar here is what I got
Oh Mary Poppins
Some people fall, they get their hearts broken, fall over themselves and stumble
Some days you'll feel like you want to die but just keep your head up, try and get another spoonful
With a little help from my friends here's what I know:
Life might be a roller coaster, but you'll get back up
Oh Mary Poppins, with a spoonful of sugar
Oh Mary Poppins, she can take a bust and make it glorious
Oh Mary Poppins, with a spoonful of sugar
You'll keep on going on till the very end of it all.
Just keep your head up and don't you worry about a thing
Because I know just what to do and it's a cinch
You'll find your way through the darkest night
With a spoonful of sugar here is what I got:
Oh Mary Poppins.
