"Happy Days" is an American television sitcom with a total of 255 half-hour episodes spanning eleven seasons. Created by Garry Marshall, the series was one of the most successful of the 1970s, an idealized vision of life in the mid-1950s to mid-1960s Midwestern United States. Starring Ron Howard as teenager Richie Cunningham, Henry Winkler as his friend Arthur "The Fonz" Fonzarelli, and Tom Bosley and Marion Ross as Richie's parents, Howard and Marion Cunningham. Happy Days became one of the biggest successes in television history and heavily influenced the television style of its time.

The Tuscadero sisters were Pinky (Roz Kelly) and Leather (real-life rocker Suzi Quatro). Leather, a reform school graduate, fronted the band. The Suedes were originally Bertie and Gertie, but in a later episode are Millie and Jillie, although, in one episode, Joanie Cunningham (Erin Moran) becomes a Suede or at least tries.

In the pilot episode, Richie Cunningham asks Al to give the fresh-from-reform school, Leather Tuscadero, and her do-wop back-up girls, the Suedes, an audition at Arnold's Drive-In. But Leather had previously stolen Fonzie's wallet when last they met and the Fonz isn't sure she can be trusted. Later, in seven episodes of "Happy Days" in Seasons 5 and 6, she began dating Ralph Malph.

Suzi Quatro, a singer-songwriter, multi-instrumentalist and actress, was the first female bass player to become a major rock star, breaking a barrier to women's participation in rock music.
