I guess Morrison was on point when they said that this version of Black was basically Johnny Rotten
I actually like how off-brand Clark is here, particularly picturing the Clark from Morrison’s AC run in this context. He’s old, grizzled, he failed (and admits as such), and he’s now a different person. I can also see how some would want to view this story as out of continuity, Elseworld, etc.
So the bigger question is, if Black is Johnny Rotten, then who’s Sid Vicious
