The 126th Army Band on Monday treated Spectrum Health employees to a shift change they won’t soon forget.

The band, hailing from the Michigan Army National Guard headquartered at the armory in Belmont, Michigan, delivered an unforgettable performance for staff during the afternoon shift change at Spectrum Health Medical Center in downtown Grand Rapids.

The musicians gathered on a nearby football field to serenade the medical team members. The band usually plays a large concert during its annual training, but current precautions surrounding COVID-19 forced the artists to adapt their approach.

The result? Once-in-a-lifetime, customized outdoor performances—including Monday’s tribute to first responders and health care heroes.

The band will be playing several concerts in Michigan.

The 126th Army Band traces its heritage back to the Spanish-American War of 1898. It’s officially designated as “The Governor’s Own.”
