President Barack Obama sure knows how to make numbers go up -- numbers in record sales, that is.

One week after belting out Al Green's Let's Stay Together, the president is credited with helping out with sales of the 1971 hit.

More than 16,000 copies of the song were downloaded in the week ending Jan. 22, according a Nielsen SoundScan report obtained by The Hollywood Reporter.

That's a 490 percent spike in sales for the song.

On Jan. 19, President Obama borrowed a few phrases from Green's hit during a fundraiser at the legendary Apollo Theater in the Harlem section of New York.

Those guys didn't think I would do it ... I told you I was gonna do it, I told you I was gonna do it, the president said, following his performance in front of 1,400 supporters.

The sandman did not come out. Don't worry, Rev, I cannot sing like you, but I just wanted to show my appreciation, he added.

The next day, Green shared his two cents on what he thought of the president's performance, which has now gone viral on YouTube.

He nailed it ... I was thrilled that the president even mentioned my name, and if the president can get the economy going again and get everything going that he wants to, then we'll all be together, Green told TMZ.

The Harlem fundraiser was one of four events Obama attended last week.

The president also made stops at the Upper East Side restaurant, Daniel (with two dinner fundraisers) and the home of movie director Spike Lee.
