Michael Rosman recommended Paul Simon's "Father and Daughter" for Father's Day, and I can't think of a better song for today. It begins:

If you leap awake
In the mirror of a bad dream
And for a fraction of a second
You can't remember where you are
Just open your window
And follow your memory upstream
To the meadow in the mountain
Where we counted every falling star

I believe the light that shines on you
Will shine on you forever
And though I can't guarantee
There's nothing scary hiding under your bed
I'm gonna stand guard
Like a postcard of a Golden Retriever
And never leave till I leave you
With a sweet dream in your head

The song, written for The Wild Thornberrys and was nominated for an Oscar. Here's the video and a live performance. Happy Father's Day.
