[Linderpat]

this concert is also referenced in the lyrics of American Pie by Don McLean:

Oh, and there we were all in one place
A generation lost in space
With no time left to start again
So come on, Jack be nimble, Jack be quick
Jack Flash sat on a candlestick
'Cause fire is the devil's only friend

Oh, and as I watched him on the stage
My hands were clenched in fists of rage
No angel born in Hell
Could break that Satan's spell

And as the flames climbed high into the night
To light the sacrificial rite
I saw Satan laughing with delight
The day the music died

The above are references to the Stones at that concert, where the Hells Angles were the security (imagine that - wonder how things got out of control:-))
