But when the program ended and representatives of the local emergency services marched from the Robe-Ann Park bandshell stage to the shelterhouse on the hill, the audience spontaneously burst into applause.
It was truly a heartfelt moment on the heart-tugging anniversary of a heart-wrenching day.
State Rep. Jim Baird, a Greencastle resident himself, provided the opening remarks, reflecting on how the aftermath of 9/11 underscores how we can all "take pride in the resolve we have as individuals and as a people ... God bless America."
That would become a common and popular theme on an afternoon that began under cloudy, gray skies but evolved into a canopy of sunshine for most of the observance.
They then joined voices to emphasize then-President George W. Bush's response to the "evil, despicable acts of terror."
Greencastle Fire Chief Bill Newgent next spoke on behalf of all first-responders, detailing how he learned of the 9/11 attacks and what he felt when he did.
"He said, 'I've got to go' and then one of my firefighters said, 'You have to come see what's happening on the TV.'"
Of course, what he saw was the World Trade Center afire and America under attack.
"My first reaction," Newgent said, "as a first-responder was to want to respond."
And 10 years hasn't changed that.
Response, training, preparation and utilization of personnel have all been impacted, Newgent said, by what transpired in the skies and on the ground in New York City that horrific day, as well in Washington, D.C., and the hills of Pennsylvania.
He said Putnam County should be proud of the 350 men and women who have been trained as first-responders and remain ready to react to local emergencies.
"We are blessed as a community to have such dedicated men and women in our own emergency services," Newgent praised.
Greencastle Mayor Sue Murray read from President Bush's recollections of Sept. 11, 2001 and quoted from the lyrics of Bruce Springsteen's post-9/11 song about a first-responder, "Into the Fire."
"Love and honor called you to duty in a higher place ... up the stairs and into the fire."
She then asked for the crowd to share a moment of silence for all those who lost their lives and/or loved ones on 9/11.
That done, the emergency services personnel and other dignitaries left the stage in silence but finished their walk between the lawn chairs and appreciative spectators to a crescendo of applause.
