Should I know those people?
Look at the author.
Tommy Shaw the long blonde hair in the front with a goatee... he was in a band called STYX which was a popular band in the ‘70s. The lead guitarist player is kind of the big blonde guy to the right of the long haired blonde guy and maybe the drummer’s in there maybe the bass player.
The keyboard player is probably not in this picture because he was kind of loathed towards the end. He was really driving the band into his direction rather than the band and working together in collaboation. Tempers flared.
IMHO, they are kind of what bubblegum music became in the late ‘70s, something akin to “Fanzine” artists for the most part.
