From the guys who brought you "Part of Your World" and "All I Want For Christmas," Life of Dad is back with their latest hit, "Somewhere Over the Rainbow." This rendition is particularly touching, as it features dads with their kids who have congenital heart defects (CHD).

Tom Riles, CEO and Founder and founder of Life of Dad, says this video is special to him because when his daughter was just 3 days old, she underwent life-saving surgery for a congenital heart defect.

"My wife and I have made many great friends in the CHD community, and this community is always looking for something to grab on to... one message that shares everybody's story," Riles told the Huffington Post in an email. And so, "Somewhere Over the Rainbow" was born. Watch the video above and don't be shy about singing along (we sure did).
