Continuity mistake: When Tanya is singing "Does Your Mother Know", she walks away from the bar and goes out to the beach to join the crowd of men who are dancing. As she's walking, there's a side shot of her, and in the background you see an extra with a towel around her waist wearing red wayfarer sunglasses. But then there's a face-on shot of Tanya, and the extra's sunglasses have disappeared. (01:10:30)
