Answer 1

Explanation:

And all I ask is a tall ship and a star to steer her by;

And the wheel’s kick and the wind’s song and the white sail’s shaking,

And a grey mist on the sea’s face, and a grey dawn breaking.

I must go down to the seas again, for the call of the running tide

Is a wild call and a clear call that may not be denied;
