JCS transposed into the present with Jesus and the disciples as anti-capitalists, the pharisees are corporatists/bankers, Pilate is a judge and Herod is some sort of game show host or entertainer.
The lyrics simply don't make any sense when sung in these circumstances. The Temple is now a nightclub called "The Temple", so when Jesus sings "my temple should be a house of prayer", it just makes you think he must have been the previous owner. Herod, Pilate and the Pharisees are all part of the same culture as opposed to Romans and Jews so again it simply just doesn't work.
Musically the band is very good, better than the movie and almost as good as the original concept album. The singing is generally very good with Tim Minchin being easily the weakest link, he sings through his nose. Jesus is very good and Mel C sings well, although she is just doing a direct copy of how Yvonne Elliman did it, not that that's a bad thing.
Last Christmas I saw the Court Theatre production here in Christchurch. Much lower budget, much smaller cast, much superior.
