Looks like he blew them all away.

Attorney General William Barr surprised attendees at the US Attorneys’ National Conference on Wednesday morning by performing “Scotland the Brave” on the bagpipes.

Barr was joined onstage by the NYPD Emerald Society, a pipe and drum band, who were performing before his scheduled remarks at Justice Department headquarters in Washington, DC.

The attorney general, a longtime bagpiper, sat on stage watching the performance before rising from his seat and retrieving the instrument and joining in.

“Now how was that for an icebreaker?” he asked after finishing the song.

Barr later explained that the performance came together as the result of a botched surprise.

“[My staff was] going to surprise me by having the Emerald Society pipe band come down from New York, but as you know I’m very proficient at — dare I say the word — spying,” said Barr, who added, “And I discovered the plot, and so this was my counter-surprise.”

This is not the first time Barr has surprised audiences with an impromptu bagpipe performance.

After being sworn in as attorney general by President George H.W. Bush in 1991, Barr surprised guests by playing his favorite instrument during a reception in the attorney general’s conference room, according to CNN.

Barr told conference attendees Wednesday that the last time he played the bagpipes was at his daughter’s wedding in December, just one day after his nomination to be attorney general was announced.

He said his daughter joked that he would upstage her at the wedding, which he responded to by saying that she was changing her name, “just before the name Barr is dragged through the mud.”
