This song's title [& locale] depends on where it is chosen to be set.

I believe Patrick Street [from which the group took its name, presumably] was the"Sailortown" of Belfast. Barrack Street, which became the preferred title for a while after Nic Jones recorded a particularly fine version some years ago, was in Halifax Nova Scotia. The DT title, Peter Street, I believe refers to streets near the docks of both Liverpool and Glasgow. Being a Londoner, I generally sing it as Ratcliffe Street

Any other Sailortown 'Streets' where the sailor met his fate?
