Even the Marine Band, considered the creme de la creme of U.S. military musicians, can have a bad day.
While it is known as "The President's Own," a subgroup of the band failed its commander in chief--and on the anniversary of America's independence of all days.
After President Obama delivered remarks to a group of visiting U.S. troops on the White House's South Lawn, a subgroup of the Marine Band began playing as he and first lady Michele Obama were chatting with soldiers.
Standard pomp for a White House July 4 ceremony, right? It was. But then the band began playing a song from country music singer Rodney Atkins called "It's America."
Obama's presumptive opponent in November's election, Republican Mitt Romney, frequently uses that very song on the campaign trail as a walk-out tune, according to a White House pool reporter, who described the scene as an "awkward moment."
