In 1975, Laurence, along with Tucker and soon-to-be-Supreme Susaye Greene, together with others added backing vocals to Stevie Wonder's Songs in the Key of Life, which was released in 1976. The same year, Laurence teamed up again with Tucker, this time under the name The Wilton Place Street Band. Under the leadership of Laurence's then-husband, the record producer and musician Trevor Lawrence, they recorded "Disco Lucy", which was a re-working of the theme tune to the I Love Lucy show.
