Call John the boat-man, call, call a-gain. For loud roars the tempest and fast falls the rain. Johnny is a good man, he sleeps so very sound, His oars are at rest and his boat is aground Red rolls the river, so rapid and so deep; Well the louder you call him, the faster he'll sleep!

Another round from Capt. Patrick Tayluer. The second voice begins at the fifth measure, i.e., during loud roars the tempest.
