The version I remember is slightly different, and from memory goes:

Now Harry was a bolshie, was one of Lenin's Band,
'Till he was foully murdered by a reactionary hand.
A reactionary hand, a reactionary hand,
'Till he was foully murdered by a reactionary hand.

Now Harry went to heaven, he fell down on his knees
I want to speak to Comrade God, I'm Harry Pollitt please
I'm Harry Pollitt please, I'm Harry Pollitt please,
I want to speak to Comrade God, I'm Harry Pollitt please

They dressed him in a nightie, with a bible his hand
And he played the Internationale in the hallelujah band
In the hallelujah band, in the hallelujah band
He played the Internationale in the hallelujah band

They put him in the choir, the hymns he did not like
So he organized the angels and he brought them out on strike
He brought them out on strike, he brought them out on strike
He organized the angels and he fetched them out on strike

One day as God was walking around the heavenly state
He came on Harry chalking Party Slogans on the gate
Party Slogans on the gate, Party Slogans on the gate
He came on Harry chalking Party Slogans on the gate

They put him up for trial before the Holy Ghost
For spreading disaffection amongst the heavenly host
Amongst the heavenly host, amongst the heavenly host
For spreading disaffection amongst the heavenly host

The verdict it was guilty, and Harry said 'That's swell'
He tucked his nightie 'round his knees and he floated down to hell
He floated down to hell, He floated down to hell
He tucked his nightie 'round his knees and he floated down to hell

Now seven long years have past, and Harry's doing well
They've made him people's commissar for the whole of Soviet hell
For the whole of soviet hell, the whole for Soviet hell
They've made him people's commissar for the whole of Soviet hell

Now seven more years have past, still Harry's doing well
And all the little Devils have joined the YCL
Have joined the YCL, have joined the YCL,
And all the little Devils have joined the YCL

I'm sure there were other verses, but the memory fails
