Four "new" MK songs thrown out is quite a bit disappointing...
Yes, in a way. As Guy says, a musical is always evolving. Maybe they thought that songs didn't work, or maybe those songs are merged with the new reprises, i remember that the Edinburgh shows had a reprise of "filthy dirty rich" inside of "Big Mac", now that reprise is after "cheerio a way ye go", I'm quite curious about all these new arrangements.
I remember reading about "the last ship" by Sting representations a s how it changed from one to the next, and I understood what Guy meant when he says a musical is always evolving.
I also remember that some song titles appeared on iswc-net, like " a wee pint" or "you can't eat scenery" that didn't made on the musical, and also "I hope you haven't changed on me", played during the first previews that gone after the press night...
At least there is one audio recording of Edinburgh with those songs that are missing. If the musical gets released on cd anyday, it would be after London shows, if that happens, and who knows how much songs would be there!
