Kramer’s new buds are 20 Marines and sailors who were wounded while serving in Iraq and/or Afghanistan and are currently receiving treatment at the National Naval Medical Center.

“I can’t think of a better gift to receive on my birthday than to have the privilege of sharing a night of our music with these brave and heroic warriors who have been wounded in the service of our country,” Kramer said.

The USO helped arrange for the military personnel to attend tonight’s Aerosmith concert. For more information on the organization, please click here.
