Well-known jazz musician and entertainer Harry Connick Jr. has written a song to help a former Winnipeg family who lost their little girl in the Newtown, Connecticut mass shooting last year.

Love Wins is the name of the song he wrote for six-year-old Ana Marquez-Greene. She was the daughter of Jimmy Greene, a saxophonist and a long-time friend and band member of Harry Connick Jr.

She was one of 20 students and six staff members killed at Sandy Hook Elementary School after a gunman opened fire on Dec. 14 before taking his own life.

The family had recently moved from Canada to the U.S. The song Love Wins will be released Tuesday with all proceeds going to a fund in her name to help her family.

Connick sang at Ana Grace's funeral and says he was inspired by a speaker at the service who said love trumps the greatest tragedies.

"It's an all-star cast, featuring Kim Burrell, Doobie Powell, Nikki Ross, Jonathan Dubose Jr., and, of course, Jimmy Greene on tenor saxophone," Connick wrote on his Facebook page.

"I hope that everyone will be able to download the song... Ana Grace used to say 'love wins' —and you know what? it always does!" he continued.

Connick Jr. said 100 percent of the proceeds from downloads of the song on iTunes will go to a fund to help Ana's family. Connick's new album Every Man Should Know is also to be released Tuesday.
