Perhaps the most impressive challenge that Palmer and the other cast members had to overcome were their dramatic quick changes.
"I honestly owe that to my Broadway performance of Cinderella, because that's how I learned to do a quick change," said the 22-year-old actress, who played Marty.
During her big solo, "Freddy My Love," Palmer had to wear three dresses at the same time -- one on top of the other -- to make it easier to slip in and out of her wardrobe for the quick transitions.
"[Costume designer] William Ivey Long, he actually worked for some time with a magician, so he's all about being able to create these illusions," she said of that particular moment.
The anticipated Grease: Live! performance became that much more heart-wrenching due to the death of Vanessa Hudgens' father just one day before they were set to go live. Hudgens' boyfriend, Austin Butler, tweeted afterward that her rendition of "There Are Worse Things I Could Do" had him "in tears."
