backtothemusic, in what way am I "strangely quiet now about the four verses, their longevity and origin" ??

The four version "full song" is a recent fabrication.
There were only four LINES, for a year now.

It is only NOW that somebody has penned a "full version".
(Interesting to read another thread on here about "Traditional singers altering songs", and how lyrics are often added in large amounts to pad out tunes.)

This is plainly what has happened here.
The chant became infamous and one or two people have just created a complete "whole" song.

Origin of the song ? "From a more thorough trawl of youtube it looks like the shameful song's authors look like their Australian Rangers fans."
It's pretty likely that the fabricated "whole song" was composed by Rangers fans.
However, there is NO evidence at ALL to support ANYTHING about a "whole song" existing more than even a month ago.
Nothing.
Not a thing at all.

It is EXTREMELY unlikely that a "whole song" like this would have been doing the rounds for a long time and NOT be recorded for posterity on an older lyrics site somewhere, or indeed recorded on YouTube on an older video.
As every other football-related fans' song is.

You talk of obfuscation, but unfortunately it is yourself who would appear guilty of that.
Where's your evidence ??

And as for calling it a "shameful song", well the four line chant isn't shameful.
It has as much humour as Alan Partridge's line:
"At the end of the day, they will pay the price for being a fussy eater. If they could afford to emigrate, they could afford to eat at a modest restaurant."

Or Denis Leary's suggestions (45 seconds in) about how the Famine could have been averted:

Or even the former Celtic player Charlie Nicholas himself who agreed with a fellow matchj commentator's groan about Celtic fans singing The Fields of Athenry with the comment: "Aye, and they're all eating chips singing this."

From a satirical comedian, an Irish-American Catholic comedian, and an ex-Celtic player.
Let the condemnation begin ...

Four lines seem to have hurt so much, even although they were sung by people whose ancestors also suffered.

Isn't it strange how Rangers fans must be censored for humour, and yet Celtic fans can't even be chastised for anything ?
