Sam and Joel return to normal hosting duties this month with a packed episode. They reflect on the recent Worship Songwriting Retreat, discuss how to encourage more female songwriters, dissect the classic song 'Cornerstone' including plenty of listener interaction, consider the limits of poetic and archaic language, and get neurological when exploring how our brain function relates to rules and variations in songwriting technique. The featured song is 'When God's perfect plans (Jesus, Lord of peace)' by Andy Clark, recorded live at the retreat concert night.
