The 42-year-old singer surprised commuters in London on Monday when she held an impromptu performance on a piano donated by Sir Elton John at London's St Pancras International Station. Alicia, who is a classically trained pianist, performed several of her hit songs, including 2009's Empire State of Mind, 2003's If I Ain't Got You and 2007's No One, as well as her latest track Lifeline, which will appear in the upcoming film The Color Purple. Before she arrived at the train station, the Girl on Fire hitmaker took to her Instagram Stories to alert her fans of the surprise performance.
