President Obama can sing, and pretty well for that matter. He showed his appreciation for Al Green on Thursday by delivering lines from Let's stay together at a fundraiser in Harlem's Apollo Theater.

The audience of 1,400 supporters, including legendary singer Al Green, went wild when Obama launched into a perfectly pitched rendition of the classic hit. ( Scroll down for videos)

I.....so in love with you he sung with a sheepish shy smile. Those guys didn't think I would do it. I told you I was going to do it, Obama said. The sandman did not come out. Don't worry, Rev., I cannot sing like you, but I just wanted to show my appreciation.

Al Green and India Arie also performed at the fundraiser, one of three events Obama attended on Thursday. Tickets for the events were priced between $100 -$200 but the president's first fundraiser started at an Upper East Side dinery, with tickets at $500,000. According to Politico, the president raised at least $3.1 million for his reelection campaign through the events.

Some tweeted that the lyrics of Al Green's Let's stay Together, underscored the themed of the president's reelection campaign.
