This performance by Katy (aka Keti, Kitty Katie) is from the 1954 Egyptian film ‘Ismail Yassin’s Ghost’ (عفريتة إسماعيل يس).  Katy plays a nightclub dancer who is murdered by the evil henchman (Farid Shawki) of a nightclub owner (Seraj Mounir ). She then reappears as the ghost of the title and haunts her co-worker at the nightclub (Ismail Yassin) insisting that he find those responsible for her death.  Unfortunately she doesn’t know ‘whodunnit’ as she was asleep at the time! Also starring were Mary Munib, Ferdous Mohamed and Zeinat Sedki.  You can see several other clips from this movie featuring a performance by Fifi Salama and more clips of Katy on this channel.
