I think it's amazing that we finally have the ZOO TV and Popmart tours now on DVD with excellent picture and sound upgrade. Alot of work must have gone into producing these DVDs and they have done a great job.
However seeing as the Elevation and Vertigo tours have had two (possibly three for the vertigo tour) DVD releases, i think the Zoo TV and Popmart Tours deserve another release some time in the future and incude some tracks that wern't included on the current releases. Ultra Violet, Wild Horses, Zooropa come to mind for Zoo TV. Miami, Do You Feel Loved, If God Will Send His Angels for Popmart.
But if this never happens im just glad that we have at least one DVD of these tours. They could of quite easily been forgotten about like Red Rocks and Lovetown and we may of never had anything.
