Barr noted it was the first time playing since his daughter’s wedding in December, a day before he was nominated to be attorney general, and did so as a surprise after hearing the Emerald Society pipers were coming in.

'[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,' Barr said. 'And I discovered the plot, and so this was my counter-surprise.'

He even competed in the World Championships for bagpipe playing.

In 1991 after he was sworn in as attorney general by President George H.W. Bush he bust out his bagpipes during a reception for a surprise performance in the attorney general conference room.

He’s served as a board member of the U.S. Piping Foundation from January 2017 to December 2018.
