The 14-time Grammy Award winning singer and songwriter said performing in a place of worship was "a real honor" and added that there was "an energy there that's very different."
Alongside old favorites, Keys on Monday night treated the 1,000-strong U.K. crowd to songs from her highly anticipated new album "Girl on Fire," saying afterward that it was incredible to see people get into the new tracks.
Since releasing her debut album "Songs in A Minor" Keys has sold more than 30 million albums worldwide. "Girl on Fire" is set for release Nov. 26.
