There are actually 4 Tempe shows from 1987.
4-2-87 Tour opener
4-4-87
12-19-87
12-20-87 tour closer
12-19-87 is the common Tempe show that circulates as it is from a pro shot video and is pretty good quality. Its incomplete but pretty good. There is a decent audience recording of 12-20-87 and it is a great show. 4-2-87 isnt a great show but is interesting as Bono's voice is completely shot.
