\begin{altverse}
O, well for the fisherman's boy,\\*
That he shouts with his sister at play!\\*
O, well for the sailor lad,\\*
That he sings in his boat on the bay!
\end{altverse}
\begin{altverse}
And the stately ships go on\\*
To their haven under the hill;\\*
But O for the touch of a vanish'd hand,\\*
And the sound of a voice that is still!
\end{altverse}

Break, break, break\\*
At the foot of thy crags, O Sea!\\*
But the tender grace of a day that is dead\\*
Will never come back to me.
