Didn't they do a abridged wicked show at Universal Japan that was about 25 minutes long?...I too like the ideas of both Wicked & Ghostbusters. Far apart on the entertainment spectrum, but good fun both of them.
.Wicked the musical, as featured in a special 30-minute condensed version for Universal Studios - Japan. The arrangements for this show do not give away any of the "surprises" of the Broadway version of Wicked the Musical. Instead the audience is treated to a selection of songs that are sure to entice viewers into buying tickets to see the full-length musical
So its pretty much a singalog with no cool effects
