Redbornstoke Morris sing the first verse as a once-to-yourself at the start of the Ampthill dance that goes with the tune. They got the song from an old BBC 'Singing Together'songbook

"On a harbour wall in a sailor's hat
is an old grey man with an old grey cat
and he dreams all day of the time he twirled
in a sailors hornpipe round the world
it was many a weary year ago
that he started off on nimble toe
for to win the prize of a silver pound
he must dance the world around"

They were going to sing the last verse at the end of the dance but you need to be able to breathe to do that
