Walking-songs

A Walking Song is the name given to the song that Frodo Baggins, Peregrin Took, and Sam Gamgee are singing just before they see the Black Rider a second time while walking to Crickhollow. Bilbo Baggins wrote the lyrics to an old tune.
While the song isn't in The Fellowship of the Ring (film), most of the last verse has survived as the song Pippin sings to Denethor while Faramir is attempting to retake Osgiliath.

Lyrics

Upon the hearth the fire is red,

Beneath the roof there is a bed;

But not yet weary are our feet,

Still round the corner we may meet

A sudden tree or standing stone

That none have seen but we alone.

Tree and flower and leaf and grass,

Let them pass! Let them pass!

Hill and water under sky,

Pass them by! Pass them by!

Still round the corner there may wait

A new road or a secret gate,

And though we pass them by today,

Tomorrow we may come this way

And take the hidden paths that run

Towards the Moon or to the Sun.

Apple, thorn, and nut and sloe,

Let them go! Let them go!

Sand and stone and pool and dell,

Fare you well! Fare you well!

Home is behind, the world ahead,

And there are many paths to tread

Through shadows to the edge of night,

Until the stars are all alight.

Then world behind and home ahead,

We'll wander back to home and bed.

Mist and twilight, cloud and shade,

Away shall fade! Away shall fade!

Fire and lamp, and meat and bread,

And then to bed! And then to bed!

Film Lyrics

Home is behind

The world ahead

And there are many paths to tread

Through shadow

To the edge of night

Until the stars are all alight

Mist and shadow

Cloud and shade

All shall fade

All shall

Fade
