It's been five years since Zach Sobiech of Stillwater passed away.

Well, I'm a sap, so it's no surprise this video left me in tears.

You may recall the 2012 viral hit song "Clouds" by Minnesota-native Zach Sobiech.

At the time, Zach was battling bone cancer. He passed away the following year at the age of 18.

But his legacy has lived on over the past five years in his song "Clouds" as hundreds of people come together to sing his song and raise money for the Children’s Cancer Research Fund and Gillette Children’s Specialty Healthcare.

Well, this past Friday night, hundreds of people came out to the Mall of America for the 6th annual Clouds Choir for a Cause and to sing Zach's song. Clearly, it had many there in tears, and it will probably have you in tears, too.

Star Tribune, more than $600,000 had been raised by night's end to benefit the Children’s Cancer Research Fund and Gillette Children’s Specialty Healthcare. Actor Justin Baldoni of TV show "Jane the Virgin" was also there to share the exciting news that a book written by Zach's mom in 2014 titled "Fly a Little Higher," was set to be produced as a film in 2019 and directed by Baldoni himself.

To date,

over $1.5 million has been raised in Zach's honor.
