[NightKnight]

"Gil-Galad was an elven king
Of him the harpers sadly sing
The last whose realm was fair and free
Between the mountains and the sea

His sword was long, his lance was keen
His shining helm afar was seen
The countless stars of heaven's field
Were mirrored in his silver shield

But long ago he rode away
And where he dwelleth none can say
For into darkness fell his star
In Mordor, where the shadows are"

Not sure what it's called, but it's the one that Sam sings on the way to Rivendell.
