Country music superstar Kenny Chesney has established a new charity to aid those affected by the Boston Marathon bombing.

The Spread the Love Fund will help pay for prosthetics and physical therapy for those who lost limbs and suffered life-shattering injuries in the blast on 15 April (13).

All proceeds from download sales of Chesney's new song Spread the Love, which features the Wailers Band, will benefit his new initiative.

He says, "It's hard to imagine a world where taking your children to school, going to the movies or witnessing something as iconic as the Boston Marathon is a dangerous thing to do.

"For me, I want to help give these people as much of their lives back as possible, but I'd also like to counteract some of the negativity in the world... Remind people that there are more good people out there, and it's up to us to spread the love."
