There's another song from Scotland to the same tune, written by - you guessed it - Jim McLean and dealing with sectarianism in Glasgow:

THEY DON'T WANT TAE KNOW
(Jim McLean)

Chorus:
Hello, hello, we're orange and we're green
Hello, hello, we toast the pope and queen
We argue about fitba' and we're living in a dream
And we don't want to know, no we don't, no we don't
We don't want to know, no we don't

Your pal is called Macdonald and he hates the Campbell clan
He talks about a massacre, and him an Orangeman
But tell him that King Billy signed the dirty stinking plan
He'll no want to know, no he'll no, no he'll no
He'll no want to know, no he'll no

Your other pal's a Celtic fan and he comes frae Polmadie
He waves the Irish banner just because he is RC
But tell him that Saint Patrick was a Scotsman and you'll see
He'll no want to know, no he'll no, no he'll no
He'll no want to know, no he'll no

Repeat 1

There's some folks sing The Soldier's Song and some God Save the Queen
There's some ? the royal blue and some the emerald green
Instead of fightin' for their rights they fight aboot Jock Stein
And they don't want to know, no they don't, no they don't
They don't want to know, no they don't

So if you follow Rangers or you are a Celtic fan
Don't belt the bloke beside you 'cos' your team lost 7:1
Remember that he's just like you - a Scottish workingman
He'll no want to know, no he'll no, no he'll no
He'll no want to know, no he'll no

Repeat 1


And the Civil Rights movement in Northern Ireland used the tune, too:

THE LONG MARCH TO DERRY
(Anon?)

Chorus:
Hurrah, hurrah, we proudly march along
Hurrah, hurrah, we sing our marching song
The battle cry of liberty went ringing loud and clear
All on the long march to Derry

'Twas on the first day of the year in nineteen sixty-nine
We gathered at the city hall, the weather being fine
With McCann in first to lead us, Michael Farrell in the van
Off on the long march to Derry
As we approached to Antrim town the bridge we found was blocked
There stood a certain major with a feather in his hat
No Fenian folk will e'er pollute this sacred ground we hold
We'll soon stop your long march to Derry

Now Toomebridge town was good we found, the people stood and cheered
And everyone supported us wherever we appeared
We crossed the bridge where McCorley died with our banners flying high
Off on the long road to Derry
'Twas in Dungiven Farrell stood and told the watching crowd
We're marching for our civil rights, we're marching and we're proud
And every man and woman here regardless of its creed
Should join in the long march to Derry

They ambushed us at Irish Street(?) and at Burntollet too
And the air was thick with stones and bricks and the missiles fiercely flew
But we got up and struggled on though battered black and blue
To finish the long march to Derry
Well now the march is over we can lay our banners down
For the world has seen what Ulster's like while loyal to the crown
And generations yet unborn will live to toast the boys
Who went on the long march to Derry

I got this off an album by 'Owen McDonagh and the Bogside Men' called 'Songs of Civil Rights' and made some time in the early Seventies, but there wasn't much info on the sleeve so I've no idea who wrote this and the other songs. If anyone happens to have access to this album, would you mind PMing me, please?
