CHANHASSEN -- The owners of the downtown Minneapolis nightclub where Prince's "Purple Rain" was filmed are holding an all-night dance party in his honor.

First Avenue owner Dayna Frank says the club wanted to give people a place to share their emotions and celebrate Prince. Entry to the event is free.

The 57-year-old singer died today (Thursday) at his suburban Minneapolis compound. His death is under investigation.

Scores of people came to the club today (Thursday) to leave bouquets, balloons and a guitar under the star that honors Prince on the club's exterior wall. Frank says everyone at the club is devastated.

Prince last played the club in 2007.
