@Nucky Nolan You're referring to The Romantics, from Detroit. Although Don wasn't yet in the band he was an integral part of the forming of Rush, The Romantics sister band.
Are you referring to the Mandela Romantics and Mandela Rush? I think that both bands were started by Stevie Nicks, who was in Heart, before she joined Fleetwood Mac, a band that evolved into Steely Dan, which was largely comprised of former members of the Doobie Brothers before that group changed its name to the Steve Miller Band, who we now know as Cheap Trick (when they're not touring as Meatloaf), and I'm sure you recall their biggest hit, "Hit Me With Your Best Shot", a song covered by Tom Petty in 2018.
