The Broadway Production of Victor/Victoria

I was revisiting the cast album and the original movie soundtrack after the news of Tony Roberts' death, and I had a couple of questions I was hoping you guys could answer:

• Does anyone know why they changed the opening number from the movie? I felt like the Broadway opening number was so much slower and plodding.
• Speaking of number changes: why did they change "The Shady Dame from Seville" to "Louis Says" in Act 2? I loved the original number. I am confused about one lyric, though, in "Shady Dame": "The rest of the tale's not a pretty one/Pity one isn't for sale."

What does that last line mean? Thanks!
