 Long after his death Barrett's son, Joe Joe, wrote "In the name of the Game", a book about how his father and other footballers such as John Joe Sheehy and Con Brosnan were joined by their love of Gaelic football but took opposite sides in the Civil War.In 2007 he was enraged when it was announced that "God Save the Queen" would be played at Croke Park due to Ireland's rugby international with England.Barrett withdrew his father's medal collection from the adjoining GAA museum in protest.
