Elton John gave a dazzling performance on the White House lawn during a musical evening hosted by President Joe Biden and Dr. Jill Biden, but it was the Rocket Man himself who became speechless and «flabbergasted» after a big surprise.The «That's What Friends Are For» singer brought his majesty and virtuous singing chords to 1600 Pennsylvania Avenue on Friday night and belted out some of his classics, including «Tiny Dancer,» «Rocket Man» and «Don't Let the Sun Go Down on Me.» The iconic songs set the mood, as the Bidens took the stage with Elton and surprised him with the National Humanities Medal.Elton's face said it all.
