Hawkwind - 'Stonehenge Decoded' "Stonehenge decoded, I was there/Sacrificed to this land so fair"

Inner City Unit - 'Stonehenge Who Knows' (Presidents Tapes lp)

The Disrupters - 'Stonehenge' (Gas the punx lp)

There was a 60s band, 'The Druids of Stonehenge' who brought a self-titled album but I can't remember what it's like.

Wojtek Godzisz - Silbury Hill (which you can hear here)

Non-specific:

Flying Saucer Attack - 'Standing Stone'
Hawkwind - 'D-Rider' "We're astral-planing, floating free/On our continuum frequency/A ring was formed out of the stone/Metamorphose, tetraform" :-)

in fact quite a few non-specific and don't forget the 'Mystic Stones' label!
