Doubts Even Here: "Doubts Even Here" is the seventh track of eight on New Order's debut album "Movement", released on November 13, 1981.  After the death of Joy Division singer Ian Curtis, the surviving members formed New Order with drummer Stephen Morris's girlfriend Gillian Gilbert joining five months later.  This led to a dispute over who should fill Curtis' shoes with the lead vocalist role.  All three male members were in contention, but due to Bernard Sumner's voice being significantly different from Curtis', New Order opted for him to take the role, wanting New Order's sound to be different from Joy Division's.
