In the changes you made to reference the movie more, were those changes MTI approved and was the additional song for Mae paid for? I really don't like when directors take tons of liberties with shows and take no consideration that some of these things are written the way they are for a reason. People should respect the original writers' vision and not try to alter things just because they don't like it. If you don't like it or have to change things that much, perhaps you should find another show that might fit better with you.
I'm not just addressing you, but people in general who have made production alterations.
When I did this show, we left everything intact, didn't add any of the new songs (the only one I like is Mae's anyways, and even so I prefer the monologue that it replaces to the song). We even included the 100 Ways Ballet-even though the script suggests cutting it. The ONLY alteration we made was using two lines from the most recent movie version-which I believe were in the script- was changing "He's to thin, she's too tall" in the Telephone Hour to "She's to cool, he's too square" due to the fact that our Kim was quite short and changing "And his hobby's baking fudge" to "And he never holds a grudge" in Healthy, Normal American Boy due to the fact that a few times in rehearsal our Albert and Conrad turned the original line into a bit of something dirty.
