Susan Kay "Suzi" Quatro (born 3 June 1950) is a British-based American singer-songwriter, bass guitar player, and actor. She is the first female bass player to become a major rock star. This broke a barrier to women's participation in rock music.[
In the 1970s Quatro scored a string of hit singles that found greater success in Europe and Australia than in her homeland. But, following a recurring role as a female bass player on the popular American sitcom Happy Days, her duet "Stumblin' In" with Chris Norman reached number 4 in the USA.Between 1973 and 1980 Quatro was awarded six Bravo Ottos. In 2010 she was voted into the Michigan Rock and Roll Legends online Hall of Fame. Quatro has sold over 50 million records and continues to perform live, worldwide. Her most recent album was released in 2011 and she also continues to present new radio programmes.Quatro is known in the United States for her role as female bass player Leather Tuscadero on the television show Happy Days. Show producer Garry Marshall offered the role without an audition after seeing a picture of her on his daughter's bedroom wall. Leather was the younger sister of Fonzie's girlfriend, hot-rod driver Pinky Tuscadero. Leather fronted a rock band joined by principal character Joanie Cunningham. The character returned in other cameo roles, including once for a date to a fraternity formal with Ralph Malph. Marshall offered Quatro a Leather Tuscadero spin-off, but she refused, saying she did not want to be typecast.
