As both a Metal Guitarist and Physician, maybe I can help.
Bending over (spinal flexion) has been shown to increase lung volume at the lower extreme of Vital Capacity. Vital capacity is the maximum amount of air a person can expel from the lungs after a maximum inhalation. So basically Halford's bending over results in being able to expel more air when signing. Flextion also approximates the diaphragm closer to the iliac crests (pelvic bones) which means it is easier to increase intra abdominal pressure in this position, which further facilitates maximum amount of air expelled.
So in a nutshell ... Halford's posture allows him to sing increasingly with more force, which unfortunately becomes more necessary with age.
Bottom line ... He still sounds great!!
