Howard (or Howie as friends would call him) unfortunately died an early age in 1986, but he wrote more than 400 songs in his career including many of Connie's R&R hits that made her famous.
Prolific composer Howard Greenfield collaborated with singer/songwriter Neil Sedaka on some of Sedaka's greatest hits including "Calendar Girl," "Happy Birthday, Sweet Sixteen," and the Grammy-winning 1975 song "Love will Keep Us Together." He also wrote a number of movie theme songs, and theme songs for such TV series as Bewitched, Hazel, and The Flying Nun.
Other artists than Connie Francis who sang Howard's songs include Captain & Tennille, Cher, Patsy Cline, Neil Diamond, Everly Brothers, Johnny Mathis, Wayne Newton, Shirelles, Etta James, Air Supply, LaVern Baker, and Gloria Estefan.
