I know it as The Hippies and the Hairies O

with the words as follows:

It was late one night, Mr. Jones came home
On the 5:47 from London O
He was rich and fat, wore a big bowler hat
And he hated the hippies and the hairies o

He walked in through his mock Tudor door
And he called to his wife, "Well I'm home dear o
I'm late I'm afraid, the train was delayed
It must be the hippies and the hairies o"

Scarecely had he stepped inside
when the au-pair ran to meet him o
saying "madame is not 'ere, she is gone I fear
Away wi' ze 'ippies an' ze 'airies o"

"O bring to me my MG BGT
for the Daimler was never so speedy o
And I will drive 'til I find her alive
Or dead with the hippies and the hairies o"

So he drove East and he drove West
Until he came to a field near Knebworth o
and there she did stand, with a joint in her hand,
she was getting into Hawkwind with the hairies o

"O What makes you leave your house and car
Your washing machine and your stereo
Your children three, not to mention me
To go with the hippies and the hairies o?"

"O What care I for my house and car
My washing machine and my stereo
For a fuse I've primed and the whole lot's timed
To explode in the middle of the Wogan show"
