GREASE - Rizo lost her line.

Rizo loses her focus during the “Beauty School Dropout” song. If you pay close attention to Rizo toward the end of the song when Frankie Avalon (singer) begins walking up the stairs. You will see Rizo and Marty are holding their hands up. While that is going on pay close attention on Rizo. She pauses for a moment looking over at Marty (Dinah Manoff) to see what she’s doing. Then she looks back at Frenchy singing the rest of the song.
