 Scorpions performed their new single, on 24 March 2007 at a special concert to celebrate the 50th anniversary of signing the Roman treaty, which became the basis for foundation of the European Union.Its main theme throughout is of the future downfall of human civilization as they themselves know it.It has received good reception and brief, but high airplay on hard rock stations, but has been hampered by the Scorpions' reputation as a "classic rock" band.
