By: Liam Parker Reminiscent of Jason Robert Brown’s hit musical The Last Five Years, The Swearing Jar takes the traditional tropes of a rocky relationship and turns them completely on its head.  The Swearing Jar is a masterclass in storytelling.  What begins as a beautifully sombre tale of love and heartache accented by musical interludes of haunting beauty, descends into a striking and refreshingly human tale of sorrow, loss, and grief.
