Herbie Hancock, Jennifer Hudson, OK Go set for Obama birthday fundraiser

Herbie Hancock, Jennifer Hudson and OK Go, three artists with Chicago roots, will head up the entertainment portion of a planned birthday party and fundraiser celebrating the president's 50th birthday on August 3rd.

There's an emphasis on the word "planned" because developments on a deal to increase the debt ceiling in Congress and the Senate ostensibly could keep the president in Washington, DC as a deadline date for a final solution bumps up against the planned celebration.

The party is being hosted by Obama's Victory Fund 2012, a joint fundraising vehicle of the Obama re-election campaign and the DNC. The event is booked at the Aragon Ballroom in Chicago, and is open to the public with a campaign donation.

Hudson sang the national anthem at the 2008 Democratic convention and performed at the first State Dinner of the Obama administration.

Hancock performed at Obama's inaugural concert in January of 2009 and at a January 2011 State Dinner. That event generated some controversy when Lang Lang, a young Chinese musician who performed with Hancock, performed a song that is something of a current standard, but in the 1950's had also appeared in a Chinese film that some perceived as anti-American.
