Free ticket

I wish I could say that the Filharmonija heard my comment about being paid to visit their concerts, but today it was someone else who seems to have placed a free ticket in my letterbox, anonymously. Weird? Unfortunately that day I will be in Vienna listening to Maris Janssons and Mahler's 7th rather than attending a concert by the French Group 'NoJazz' in Vilnius. Thanks, whoever it was!
