Stan Hugill always said that shantying was not allowed in the British Navy, except for Drunken Sailor, which was a "stamp and go" shanty - the RN relied on many men to haul the sails pretty fast. I watched him demonstrate the striding back, pulling on the ropes, and he described how there would a large number of personnel ready to take the strain. He sang the shanty:

What shall we do the drunken sailor,
What shall we do the drunken sailor,
What shall we do the drunken sailor,
Earl-eye in the the morning?

HOO-YAH! and up she rises,
Patent blocks of different rises,
HOO-YAH! and up she rises
Earl-eye in the morning.
