The Catalina Wine Mixer, made famous in the legendary scene from the movie "Step Brothers," is really happening, according to the Santa Catalina Island Co.'s website.

Finally, fans of the 2008 movie will have the chance to experience the epic party in real life. The website promises a fun-filled day complete with wine, gourmet food and live music.

Best of all? The Dan Band, which has appeared in "Old School" and "The Hangover," will perform. They'll also reportedly arrive in a helicopter -- just like the band in the movie. Sadly that band, Uptown Girl -- which exclusively played 80's-era Billy Joel covers -- will not be in attendance.

There's no word yet on whether Will Ferrell or John C. Reilly will make an appearance, but here's hoping they do show up and dazzle the crowd with a rendition of "Por Ti Volare."

It all goes down on Sunday, Sept. 13, at Descanso Beach Club in Avalon, California. To find out more about the Catalina Wine Mixer or to buy tickets, head to http://www.visitcatalinaisland.com/event/catalina-wine-mixer.
