Jackson decided that the risk to her tour group is too great to continue ahead. “If anything happened to anyone on this tour, I could never forgive myself,” she explained.

The All For You tour was due to set off October 31 in Helsinki, Finland and continue around Europe until mid-December. Cities affected are Oslo, Copenhagen, Berlin, Hannover, Frankfurt, Leipzig, Cologne, Munich, Paris, Antwerp, Arnhem, Stuttgart, Manchester, Newcastle, Sheffield, London, and Birmingham.

Pop rockers Weezer have also pulled out of their European commitments, although no reason has been given yet.

The band was scheduled to kick things off in Copenhagen on October 9. Their tour, which included stops in Hamburg, Berlin, Munich, Paris, Madrid, Manchester, London, Birmingham, and Glasgow among others, was to adjourn November 1.
