*The last time we saw President Barack Obama at a Labor Day event with Aretha Franklin, it was in Detroit 2008, where he hummed a few notes of the singer’s classic “Chain of Fools.”

This year, the pair again will be on stage at the Labor Day Rally at the Hart Plaza in Detroit on Monday. The diva will perform of course “Chain of Fools” and a list of other popular songs.

At the event, Obama is scheduled to address labor union members and other attendees. It’s free and open to the public.
