This is a verse from Nic Jones' version of Barrack Street;

Well, everything being silent and the hour but twelve o'clock,
I put on the shirt and apron and steered for Cronin's Wharf;
The captain says, "Now Jack, I thought you were to Windsor bound -
Well, you might have got a better suit than that for thirty pound."

To fit the rhyme, I'm sure the words would originally have been (Cronin's) Dock.
