So it looks like I'm a few years late here. Those lyrics are mostly correct. I just wanted to update it with what i think those unsure words are.

You don't play our songs on the radio
You say they're too political
Who controls the mind where the mind's controlled
For the music on the airways
For those empty minds, those empty heads
Play songs of sex and drugs instead
Don't tell them how it really is

Must MI5 look after you
Control your thoughts with information
To your hearts and minds
To keep you all from
Thinkin', thinkin', thinkin', thinkin'

# So come all ye witches and you wizards
Conjurers and tricksters
Change our past into a future grand
So come all ye gombeen men and seàníns
Lackeys and west britons
Sing, sing for me
A rousing rebel song
And all the kids in school will sing along. #

So this is your democracy
Be silent or agree with me
We revise our past; we change our past
To suit this time and moment
For things weren't really all that bad
And Ireland's past was not that sad
Think otherwise, you must be mad

Did Queen Victoria give two thousand pounds
To the dogs and cats of Ireland during the famine
Ah but she did you know, to save them all from
Starvin', starvin', starvin', starvin'
