Most of us are probably hoping we’re still vertical and breathing by the time we hit 90. WWII veterans Marin Perryman and Paul Kopey aren’t hoping. They’re doing.

These two vets, both in their 90s, were waiting to board an honor flight at Reagan National Airport recently when a female trio, the Ladies for Liberty, starting singing an iconic tune from the 1940s.

Watch what happens when the ladies plunge into the 1940s Andrews Sisters hit, Boogie Woogie Bugle Boy:

The Ladies for Liberty is a singing troupe dedicated to performing the Andrews Sisters style of music through their own rendition of vocals, hairstyles and costumes, according to their web site.

The Honor Flight Network is “a non-profit organization created solely to honor America’s veterans for all their sacrifices. We transport our heroes to Washington, D.C. to visit and reflect at their memorials. Top priority is given to the senior veterans – World War II survivors, along with those other veterans who may be terminally ill,” according to its web site.

God bless these men for their service. ROCK ON!
