Rainer, as I remember: "Landed up in the Douglas jail - until the Dublin boat did sail, Deported every man..." The Dublin lads are locked up after the fight then deported. 'Wacker' or 'Whacker' is still a common nickname in Dublin to this day - possibly given to people who like giving out digs. It also means, contradictorily, 'shit' and, figuratively, to be afraid/chicken i.e.: 'smell o' wack' 'wacking it' You might notice that they start off the drinking in the 1st verse in Dublin - 'Weren't we the rare auld stock' ('rare auld stock' meaning 'hoors' cf. the Zoological Gardens) 'getting locked' - getting drunk. The Ace of Spades is a bar in Dublin that no longer exists (anyone remember where it was ?). They roll down to the boat over 'Butt Bridge' and then pass out the Liffey Mouth by the Alexandra Basin - part of the Dublin docks. I won't go on as I'll be here all day - I'm sure it's covered in those threads linked to anyhow...

PS Note of controversy - 'crack' is widely acknowledged as being a word of English origin
