The Schubert in Rock project, led by Austrian musician Klaus Schubert, performed in Innsbruck on December 6. It and featured quite a few members of the Purple family with Don Airey on keyboards, Neil Murray on bass, Klaus Schubert himself on guitars, and Bernhard Welz on drums; with vocal duties shared between Tony Martin, Joe Lynn Turner and Doogie White.
Austrian public broadcaster ORF has a report about the project. You can view it online at orf.at (the report starts around 1 hour mark into the show and lasts for 3 minutes).
Thanks to Andrey Gusenkov for the info.
