Electric guitar...

Try a little bit of Grinder, you’ll be rockin the Priest in no time flat! :)

A lot of Priest are fairly simple from a rhythm standpoint. Desert Plains, Living after midnight, devils child, Solar Angels

Victim of Changes is still one of my faves from them

Site call songsterr has a bunch of tabs and play though for free. Pretty cool but free has synth on playthrough, although the paid version overlays the actual song in many cases, IIRC.
