Rita Johnson + Ruth Hussey
Their scenes weren't deleted! The play the bridesmaids who run into the room when Roz and Walter are about the kiss, and urge her to change from her wedding dress so she and her new husband can escape. You can hear their voices clearly (esp Rita's little Southern accent), but those floppy bridesmaids hats cover their faces.
