In the late 1990s, Eurythmics reunited and recorded a new album, "Peace", which was released in 1999. The single "I Saved the World Today" reached No. 11 in the UK Singles Chart, and a remix of "17 Again" gave the duo their first chart-topper on the US Hot Dance Music/Club Play chart. The band also embarked on a world tour, dubbed the "Peacetour", to support the album. The tour started on 18 September 1999 at Cologne's Kölnarena and ended on 6 December 1999 at the London Docklands Arena (which was filmed and released on video and DVD). All proceeds from the tour went to Greenpeace and Amnesty International. The year 2000 saw numerous European festival appearances by Eurythmics (at Germany's Rock am Ring, among others). In 2001, Stewart performed with U2 for the benefit concert. In 2002, he collaborated with Bryan Ferry on his album "Frantic".
