The picture is a bit rough but good enough to identify the line-up of Dundee's Satan's Empire.
The band was - Derek Lyon, vocals - Bill Masterton, drums - Sandy McRitchie, guitar - Duncan Haggart, bass.
Heavy metal was their music of choice and this track below, called "Soldiers Of War", appeared on an album released in 1981 titled "Heavy Weight", a NWOBHM compilation.
They also had this track out earlier as a single (1980/early '81) but it seems to be extremely elusive, just as it is finding details about the band!
If anyone can add anything else, drop it in the comments.
Well they do say the devil has all the best tunes - so give this one a blast and see if you agree!
Thanx to Stephen.
