Party with a purpose at O’Flanagan’s Irish bar on the Upper East Side. The bar is holding a benefit tomorrow night with all proceeds going to the Firefighters 911 Disaster Relief Fund and the WTC Police Disaster Relief Fund.

The goods include tickets to Jets, Giants and Knicks games, as well as a Bjork’s concert, Broadway’s “Mamma Mia!” and tapings of MTV’s “Total Request Live,” as well as art work, dinners-for-two and clothing.

“I’ve been totally overwhelmed by the things that have been donated – the designer Angel Sanchez has donated $5,000 worth of dresses and already we have a bid of $2,000 for a pair of tickets to ‘The Producers’,” says event organizer Mark Cheffo.

O’Flanagans, 1215 First Ave. between 65th & 66th streets. (212) 439 0660.
