Well i've got a soft spot for Tulsa because i played that role. My fave bit ever though was the confrontation scene. We had a really really bad Mama Rose (one guy actually put ear plugs in when she, i use this in the loosest term possible, sang) but Louise was amazing. She was truely captivating especially when she blew her top.
Jesus Loves You... Everybody else thinks you're an idiot!
The musical is flawless, but I have to say that my favorite scene is always the one where "Louise" looks into the mirror and says: "I'm pretty. I'm a preety girl Mama". That and Louise's Strip routine in the Garden of Eden setting always "get me".
"Rose's Turn" if done just right will give you goosebumps into next century. Voice on the verge of cracking, heck Rose's sanity on the verge of cracking, mixed with hope, anger, longing...
