Teri DeSario (born November 27, 1951) is a singer/songwriter from Miami, Florida. DeSario worked within several music genres out of high school. She was vocalist, played recorder and harp from 1970 - 1977 with a Medieval and Renaissance music group, the Early Music Consort, headed by scholar and Pro Musica member Arnold Grayson. She began her popular career as a singer/songwriter in the folk genre and later expanded her love of folk music with her passion for jazz. After marrying horn player, arranger, and composer Bill Purse, they founded a pop-folk-jazz collaborative called Abacus. One night a long-haired man walked into the club where she was performing, claiming to be the producer of the Bee Gees; it turned out he actually was. Barry Gibb heard her demo of original music and was so inspired by DeSario's vocals that he wrote a song for her called "Ain't Nothing Gonna Keep Me From You" and helped her obtain a recording contract.
