Here are the people who performed live at the U.S. Army's 250th anniversary parade and President Donald Trump's unofficial birthday party.

Trump, who turns 79 on Saturday, said he wants a military parade to show how great the country is. The president first pushed the idea in 2017 after attending the Bastille Day parade and celebration in France, saying he wanted to "try and top it." That effort was canceled after price estimates topped $90 million.
