The air is rife with the tension of their history. The stakes are high, and as each composer struggles to be a 'gentleman', the song becomes a battlefield upon which they act out their sexual jealousy, professional rivalry, gender-political philosophies, and mutual sympathies in the fight for creative control. Each lyric they write, each note they choose, each chord they craft to accompany their singer's 'voice' becomes a blow or a parry in a classic duel of secret-sharing 'doubles' that is by turns comical, compassionate, and chilling.
