lively, crowded scene inside a large hall

lively, crowded scene inside a large hall. There is a stage area with people standing and dancing, some raising their arms in the air. A man in a purple shirt seems to be the center of attention, as he is also dancing. Some people in the crowd are clapping and cheering, while others are recording the scene with their phones. A guitar player is visible amongst the dancers. The background features banners that read "World Forum for Democracy" and "Forum mondial de la démocratie." The hall has a wooden ceiling. The overall atmosphere is festive and energetic.
