The Grammy-winning artist delivered a surprise performance at the St. Pancras International train station on Monday with a few of her classics. The crowd rejoiced and surrounded the singer as she sang classic hits like "If I Ain’t Got You" and "No One" while playing piano.

Keys also surprised the audience when altering the "Empire State of Mind" lyrics from "now you’re in New York!" to "now you’re in London!" She also performed her latest song "Lifeline" part of the film soundtrack for "The Color Purple," which premieres on Dec. 25.

The "Girl On Fire" singer joined the list of musicians who have performed on those pianos including John Legend, Tom Odell and Jeff Goldblum. She played on a black piano named after Elton John, who reportedly donated the instrument to the transit hub's main arcade in 2016.

Keys just finished headlining two days of the Jingle Bell Ball event at the O2 Arena over the weekend.

The singer-songwriter will embark on a semi-autobiographical musical titled "Hell's Kitchen," for which ticket sales began on Monday.
