A Tuesday news release says Chesney has established the “Spread the Love” fund with his own donation and will gift sales of his single by the same name as well. Donations will go to Boston Medical Center and other area facilities. Fans also can donate directly to the fund at BMC.org/Kenny.

The money will go to the purchase of prosthetics and fitting, follow-up care and physical therapy.

Three people were killed and more than 260 injured in the April 15 attack at the marathon finish line.

Chesney co-wrote “Spread the Love” with The Wailers. It appears on his new album Life on a Rock, out this week.
