Recipients of the 2016 Kennedy Center Honors, including Mavis Staples and James Taylor, were treated to a reception at the White House in Washington, D.C.

WASHINGTON — The longest, loudest standing ovation of the Kennedy Center Honors gala wasn’t reserved for Al Pacino, Mavis Staples or the Eagles. Instead, it went to the man sitting to their left, attending his eighth and most likely his last honors presentation: President Barack Obama.

While politics were absent from the tributes to the performers who were recognized on Sunday night, the arts community’s affection for Obama — and its nervousness about President-elect Donald Trump — was palpable in the Kennedy Center Opera House.

The president and first lady Michelle Obama were introduced last, after Pacino and his fellow honorees: gospel singer Staples; pianist Martha Argerich; singer-songwriter James Taylor; and Don Henley, Timothy B. Schmidt and Joe Walsh, the surviving members of the Eagles.

After a sustained ovation, host Stephen Colbert greeted the crowd of Washington insiders as “endangered swamp-dwellers,” referencing Trump’s “drain the swamp” campaign pledge. He joked that Obama would need to receive the honor to attend again and that “unlike the Nobel Peace Prize, they don’t just give these away.”

The Kennedy Center Honors are in their 39th year, a period that has included six presidents — three Republicans, three Democrats — and all have taken time to welcome the recipients. But the 2016 election was noteworthy for the way A-list performers lined up behind Obama and Democratic nominee Hillary Clinton, while Trump had relatively few celebrity endorsements.

Although the president has no say in who receives the awards, Colbert joked that next year’s honorees would include Scott Baio, Gary Busey and Meat Loaf.

“For the past eight years, the White House has given us a leader who’s passionate, intelligent and dignified,” Colbert said, and the crowd rose for another prolonged ovation, prompting Obama to stand and wave.

“Sir, I don’t even know why you stood up. I was talking about Michelle,” Colbert said.

Earlier, at the White House, Obama welcomed the honorees at a reception and said participating in the gala was “one of the perks of the job.”

“The arts have always been part of life at the White House because the arts are always central to American life,” Obama said. “That’s why over the past eight years Michelle and I have invited some of the best writers, musicians, actors and dancers to share their gifts with the American people and to help tell the story of who we are.”

Kennedy Center chairman David Rubenstein also thanked the Obamas, noting that the president isn’t required to attend the honors or host a reception.

Another standing ovation went to Bill Clinton, who made a surprise appearance on stage to talk about how Taylor’s music resonated with him and the American public in times that tested the nation’s resolve.

Politics aside, the honors proceeded as usual, with musicians and actors taking the stage to pay tribute to the honorees, who stood on a balcony, waving and applauding as they wore the event’s signature rainbow-colored garlands. The ceremony will be broadcast Dec. 27 on CBS
