Pogues lyric question - The Body of an American

Factual Questions
1

There’s a line in The Pogues’ The Body of an American that sounds like “With a slainte Joe and Erin go”. I’ve only found a few sites with google that has the lyrics that I searched on (“we had our first taste” and “ancient irish history”) and they all list the line as “With a slainte Joe and Erin go”. But I seem to remember that the line was something in Gaelic, with “go” being “gobh” or something like that.

Can anyone verify the line, and also translate it? “With a slainte Joe and Erin go” doesn’t seem to make sense.

Is it maybe just a form of “Erin go bragh” shortened to make the rhyme work?

3

It makes perfect sense as is. “With a ‘sláinte’ Joe and Erin go”, i.e., Joe and Erin say “sláinte” (cheers) as they go (away).

4

Slainte is a toast, roughly meaning “health”.
I would agree that “Erin go” is short for Erin go bragh.

It sounds like a “shorthand” way of saying “With many toasts…”

… and having just looked at the lyric in context, it makes a lot more sense than “Erin Go Bragh” would, quite apart from the fact that “Erin Go Bragh” isn’t a phrase used much outside North America.
