The Young'uns -- an a capella trio from northeast England -- have released "Three Dads Walking," a song dedicated to three British fathers who all lost their daughters to suicide. Andy, Tim, and Mike (pictured here with Sean Cooney, Michael Hughes, and David Eagle of the Young'uns) started their campaign to raise awareness for suicide prevention. Suicide is the biggest cause of death for people under 35 in the United Kingdom. The Three Dads have been walking the length and breadth of the UK as part of their campaign.
