jno - I was that soldier!
I was there when Black Sabbath played with their Stonehenge set, forever immortalised in the 'rockumentary' Spinal Tap.
It was a Reading Festival, and Sabbath were at one of their career low points - they had Ian Gillan on vocals, and Bev Bevan (from ELO!) on drums.
The show got off to a terrible start when coloured smoke was somewhat over-applied, and Ian Gillan disappeared coughing and choking under a cloud of it.
The show did not get better, and backstage afterwards, when I was interviewing the band, Geezer Butler threatened me if I didn't get the name of his beloved Aston Villa right in the feature.
Apparently an American journalist had somehow forgotten the Villa, and translated the name into 'Woverhampton Wolverines' and Geezer was not impressed.
Remembering that my editor at the time had been on the receiving end of a punch from Geezer over a negative album review he had penned, and had measured his length on the press junket room floor, i was delighted to confirm that I knew the name, and would be sure to get it right.
Who'd be a music journalist!!!!
Well - me actually!!
