Helen and Kay Lewis', two sisters from Michigan, names cropped up on Motown albums and some single releases in the '60s, such as Gladys Knight & the Pips' "Just Walk in My Shoes." But their careers didn't begin at Motown, rather, in the '50s as jazz singers and songwriters. After high school, Kay attended Michigan State University and earned a degree in music; Helen graduated from UCLA with the same degree.
