Quality Issue: Customers should note the picture quality of this DVD does have faults, and this cannot be fixed or replaced. The quality of the material is variable: either because it was recorded via satellite; has been converted from NTSC to PAL; or because it has been damaged over the years. The studio who released this DVD have applied modern technology to repair any damage as far as they can, and the footage has all been colour-graded. The horizontal 'banding' that appears on some of the UK performances is called microphany and occurs when the camera lens is affected by great volume.
