Priest was Glenn and KK was just kinda there filling the gaps.
I agree from a musical point of view but , as you know, from a band history point of view Glenn was recruited as a second guitarist (around the same time as Halford came in) to KK who had already been in the band 3-4 years. So , forgetting how bitter and twisted KK may get , it's understandable that he feels that authority to speak as a "founding member" along with Ian Hill if you forget the short-termers in the very early days.
I wasn't there in the early 70's (not that old ) but I think Schenker and KK were doing similar things with their image around the same time. If memory serves correct Schenker asked KK to join Scorps at one stage.
Yeah, I know all that. Maybe I was a little harsh and pg said, the writing credits are evenly split.
I just think Priest wouldn't have gotten to the heights they did without Tipton. Maybe I'm just being a fanboy too, which is entirely possible.
It would have been interesting to know the exact split of music writing over the years between the two. Can't help but to feel Glenn was the more driving force being his leads are much more frequent than KK.
I do think if KK was keen to rejoin, the band should put the rivalry between them do it. It makes sense. Richie handles all of Glenn's parts fine anyway.
