Lyric:

Dry your tears, A journey's end. The saga's done, We part as friends.

We must away, We cannot tarry. The minstrel's burden, Is ours to carry.

All other stories, Will ever pale. For we have sung, The perfect tale.

The song is a reference to "The Last Goodbye" from The Hobbit: The Battle of the Five Armies, which was written and sung by Billy Boyd.
