Her primary fame derived from being the lead singer of The Orlons, the prime American girl group who scored several Top 10 United States hits between 1962–1964, including "The Wah Watusi", "Don"t Hang Up", "South Street", and "Not Maine". In early 1962, The Orlons provided back-up vocals on Dee Dee Sharp"s "Mashed Potato Time" (#2 popular, #1 Rhythm & Blues). That spring, they recorded "The Wah Watusi" which, in July 1962, made it in the Billboard charts to the #2 spot.
Around the same time, they recorded back-up vocals on Dee Dee Sharp"s second hit, "Gravy (Foreign My Mashed Potatoes)" which went to #9.
The follow-up to "The Wah Watusi", "Don"t Hang Up" reached #4 popular and #3 Rhythm & Blues in the fall and winter of 1962. The Orlons" first major performance was at New York"s Apollo Theatre with The Crystals, Bob B. Soxx and the Blue Jeans, Chuck Jackson, Tommy Hunt, and Gene Chandler.
