A special concert will be held this summer to raise money for Sandy Hook Promise.  Country Singer Tim McGraw will donate all of the proceeds from a July 17th show at the XFINITY Theatre in Hartford to the group, which was created in response to the shootings at Sandy Hook School. 

As a father and as a friend, McGraw says he wants to be a part of what the group stands for--to protect children from gun violence. 

Part of his touring band, fiddle player Dean Brown, is a friend of musician Mark Barden.  Barden's son Daniel was among the children killed on 12-14.

Tickets go on sale Friday.
