Using female session vocalists named Ingrid, Wilma and Monica, they scored a successful single in the United Kingdom in 1975 with the song "Save Me", which peaked at #30. They later used other vocalists, such as Gitta Walther, Lucy Neale, Betsy Allen, Roberta Kelly, and Jackie Carter for their first recordings and upcoming album. Since they were only a studio group; Levay and Kunze realized then that they would need to find professional entertainers for presentation to the public. Penny McLean, Ramona Wulf and Linda G. Thompson became the public face of Silver Convention.
