Bridge over Troubled Water from Paul Simon, here in the 50-plus version in 2002 by Johny Cash with some help from Fiona Apple.

There are a few hundred cover-versions, but this one I find very touching.

When you're weary, feeling small
When tears are in your eyes, I'll dry them all (all)
I'm on your side, oh, when times get rough
And friends just can't be found
Like a bridge over troubled water
I will lay me down
Like a bridge over troubled water
I will lay me down

When you're down and out
When you're on the street
When evening falls so hard
I will comfort you (ooo)
I'll take your part, oh, when darkness comes
And pain is all around
Like a bridge over troubled water
I will lay me down
Like a bridge over troubled water
I will lay me down

Sail on silver girl
Sail on by
Your time has come to shine
All your dreams are on their way
See how they shine
Oh, if you need a friend
I'm sailing right behind
Like a bridge over troubled water
I will ease your mind
Like a bridge over troubled water
I will ease your mind

Simon and Garfunkel
