Singer-actor Harry Connick Junior has written a song in memory of a former Winnipeg girl who was killed at Sandy Hook Elementary school in Newtown, Connecticut, last December.

Connick says he hopes sales of Love Wins will help Ana Grace Marquez-Greene's family.

The six-year-old and her parents had relocated to Connecticut from Winnipeg not long before a gunman opened fire at the school, killing 20 children and six staff members.

She was the daughter of jazz saxphonoist Jimmy Greene, who taught at the University of Manitoba, and his wife, Nelba Marquez-Greene, who worked at the University of Winnipeg.
