Hmm...


Featuring Halford on vocals and harmonica, Paul Watts on guitar, Ian Charles on bass, and John Hinch on drums, Hiroshima was a local hard rock band making the rounds and sharing the '72/'73 Midlands club circuit with Priest for the better part of a year. After Ian Charles was later released, Halford took over his bass duties(!) and a few demo tapes were possibly recorded, but the group never did take off. 

Yes, I have take a look on the famous and good Info Pages.
Was right with the harmonica, but have totally forgotten the bass guitar.
