The Plough and Stars is a bar and music venue in Cambridge, Massachusetts. It was founded in 1969 by brothers Peter and Padraig O'Malley, named after the play of the same name by Seán O'Casey.[1] The Boston Globe and Boston Phoenix have noted its disproportionate cultural influence for its size, with a number of noted musicians, writers, and politicians frequenting the bar over the years.[2][3]
