Dropkick Murphys replace Yeah Yeah Yeahs at Boston Calling music festival.

The Dropkick Murphys will replace the Yeah Yeah Yeahs in the opening night lineup of the Boston Calling music festival due to the latter's vocalist and pianist Karen O being sick. The festival will feature headliners such as the Foo Fighters, The Lumineers, and Paramore, as well as other acts including Alanis Morrissette and numerous New England performers.
