The group can be traced back to a 1990 Christmas party for students of the Minneapolis School of Anesthesia. A few of the then-students were singing various songs, one of them being Neil Sedaka's Breaking Up Is Hard To Do. When a senior student suggested that the song be sung as "Waking Up Is Hard To Do", the group was formed. The group's first performance was for the graduation ceremonies of the 1991 class of the Minneapolis School of Anesthesia. This first performance was witnessed by several officers of the Minnesota Association of Nurse Anesthetists. These officers approached the group and ask them to perform at the American Association of Nurse Anesthetists' National Conference, to be held inNashville, Tennessee, late in the summer of 1991. This was the group's first national performance.
