Madonna performing at her Sticky and Sweet Tour - Live at Wembley Stadium.
London, England - 11.09.08

A committee is hoping to keep the Material Girl from taking to the stage in Warsaw on 15 August (09), which coincides with the Assumption of Mary feast - a holy date in the Catholic Church.

A Catholic Society representative maintains the controversial pop star's shows on her Sticky & Sweet tour are anti-Christian and would conflict with the religious celebration.

The group has urged Polish government officials and tour promoters to cancel the show - but if the performance goes ahead, the assembly has promised to "stifle Madonna" by staging a picket line outside the venue.

The Catholic protesters aren't the first to take issue with Madonna's current tour - last month (May09) Russian officials demanded she promise not to blaspheme at her August concert in front of the country's oldest museum.
