The Water is Wide" is a traditional folk song.  The girls have been
performing it now and then for years and years.  I've been lucky
enough to see Mary-Chapin Carpenter add a beautiful third part to the
harmony on a few occasions.
The Water is Wide.
The water is wide, I can't cross o'er
And neither I have wings to fly
Give me a boat that can carry two
And both shall row - my love and I
Now love is gentle, and love is kind
The sweetest flower when first it's new
But love grows old, and waxes cold
And fades away like morning dew
There is a ship, she sails the sea
She's loaded deep as deep can be
But not as deep as the love I'm in
I know not how I sink or swim
The water is wide, I can't cross o'er
And neither I have wings to fly
Give me a boat that can carry two
And both shall row - my love and I
And both shall row - my love and I
