Joe Biden's evening inauguration special has come to a close with a spectacular performance by Katy Perry, complete with an impressive fireworks display from the US Capitol.
Foo Fighters, Justin Timberlake, Demi Lovato and Bruce Springsteen all performed in the celebratory television special hosted by Tom Hanks, but Perry's powerful performance was just the right note to end on.
Elsewhere, a rendition of Amazing Grace by famed cellist Yo-Yo Ma had social media abuzz.
