Green was a hot topic, not only for Obama. At a Q&A session moderated by GRAMMY Museum executive director Robert Santelli, Timberlake recalled one of his favorite memories of the annual music awards show.

The 32-year-old entertainer said he was asked to perform a song at the last minute at the February ceremony. After recruiting Keith Urban and Boyz II Men for a song, Timberlake said he tried to contact Green to join them, but was unable to reach him. Suddenly, Green came running into the rehearsal clad in a mink coat, said Timberlake. “He goes ... 'I’m sorry I’m late. They called me. I was in the tub,' ” recalled Timberlake.

“So not only am I taken aback from his entrance, but now I have a visual of a holy bath full of bubbles and the Rev. Al GreenAlexander (Al) N. GreenDem rep: Trump disaster aid request is 'how you let America down again' House Dems introduce articles of impeachment against Trump Dems to launch new impeachment push on Wednesday MORE gets a phone call. And he runs into his closet — because this is how my sketch comedy mind works — he runs into his closet like Clark Kent and comes out like Superman,” Timberlake said to laughs from the crowd.

The workshop came as a precursor to a Tuesday evening event featuring performances from the workshop’s musicians. The event will be live-streamed and filmed for a broadcast of “In Performance at the White House” on PBS stations on April 16.
