text: Valerie Brown (voiced by Barbara Pariot, singing voice provided by Patrice Holloway) – The band's bassist and backup singer; most often shown playing tambourines. The voice of reason in the group, Valerie is highly intelligent and a mechanical wizard. During the 1970s, the character was known as Valerie Smith.
  Melody Valentine (voiced by Jackie Joseph, singing voice provided by Cheryl Ladd as "Cherie Moor") – The band's drummer and backup singer and a stereotypical dumb blonde. What Melody lacks in intellect she makes up for with her perpetual sweetness and optimism. Her ears wiggle whenever there is danger. During the 1970s, the character was known as Melody Jones.
  Alan M. Mayberry (voiced by Jerry Dexter) – The group's tall, blond, and muscular roadie and Josie's love interest.
  Alexander "Alex" Cabot III (voiced by Casey Kasem) – The group's band manager, highly identifiable by his brightly colored mod wardrobe, sunglasses, and idiotic promotion schemes. He is the twin brother of Alexandra. Alex is an admitted coward but is good-hearted in sharp contrast to his sister Alexandra. Alex and Valerie have a slight attraction to one another at times. He also seems to be attracted to Melody. Alex physically resembles Shaggy Rogers in Scooby-Doo. In The New Scooby-Doo Movies crossover episode "The Haunted Showboat", Casey Kasem voices both Alex Cabot and Shaggy Rogers.
