Yesterday was Memorial Day, a day to honor the memory of those who lost their lives while serving our country and show unified support for those currently serving, but for a group of active duty persons, the day before Memorial Day was an extra special day.

Brad Paisley was a surprise guest on Sunday at Bagram Airfield, the main U.S. base in Afghanistan. Brad expressed his thanks to the service members by playing an hour-long acoustic concert for about 3,000 U.S. troops and called the event "the honor of my life."

In a video posted to Instagram, Brad said "The Country Nation tour took an unexpected detour this weekend. This really is a world tour now."

Brad had to do some serious rearranging to make the concert happen. His Saturday concert in Iowa was moved to an earlier time and that evening, Brad boarded Air Force One with President Obama and made the overnight flight to Bagram. The trip wasn't announced and was a complete surprise until they landed. President Obama delivered a speech to the troops expressing thanks for their service. The President also met with military commanders and visited wounded troops in the base hospital.
