The Doobie Brothers, Could've been substituted with what group?
I remember album cover use to always have these groups looking all intimidating to where you couldn't tell if they were singers or a gang. Probably both. The episode where the Doobies stop the culprits from going through the front and back door could have easily been portrayed by these super groups of the time.
Earth Wind and Fire
Commodore
Isley Brothers
Confunkshun
Cameo
KC and the Sunshine Band
Sly and the Family Stone
Who Did I notably miss ? and don;t say Jackson 5 who were just kids themselves
