The sailor who told me in the 1940s that a killick was a leading hand, also gave me one verse of a song, sung to 'The Girl I Left Behind Me':

Oh I don't give a fuck for Donald Duck
Or the killick of the working party;
You can suck my knob for a couple of bob
And me name is Mike M'Harty

('Bob' = one shilling in old coinage = one twentieth of a pound sterling)
