Everything evolves.
Which begs, the question, how did a lineage of rock stars evolve from one another? I’ve chosen the “wild” branch of the rock-n-roll tree here (Fig. 1), a lineage told in pictures.
Did I miss anyone?
Figure 1. Evolution of rock stars beginning with Ike Turner (1951, Rocket 88) and Big Mama Thornton (1952, Hound Dog) and the rest you probably know. From sweet and clean cut rockstars evolved to become androgynous and highly decorated. Not shown: Liberace, who evolved plumage by convergence early on.
If anyone wants to parallel this lineage with the lineage of feathers in birds, crests in pterosaurs or Longisquama (Fig. 3), be my guest. So far, it seems, no reptile (including humans) have invented anything more exotic than plumage, with the possible exception of wings and flight (Fig. 2). When rockstars go “all out” they seem to move toward more exotic plumage. What goes around (in the Triassic), comes around (in the recent).
Figure 2. David Lee Roth of Van Halen demonstrating bipedal leaping and hind wing gliding, as in Longisquama (Fig. 3) and Sharovipteryx.
Have a rockin’ good day!

Where does post-beatles john lennon fit?
Good thought, but the Beatles are on another lineage. Descending from Elvis and Berry, but not from the Stones. Post-Beatles John Lennon might owe more to Dylan.
