Tampereen Teatteri (The Tampere Theatre, TT) was an important building during the final battles of Finnish civil war (1918).
Here's a sample of a ghost box session in TT. As a guest is famous Finnish rock star, Jussi Selo, on the left. When asked what is done with this (a rifle), the "ghost" replies via the box: Tapetaan*, meaning: (someone is) killed (with it). https://youtu.be/qTD1Qd_xVIk?t=11m https://youtu.be/qTD1Qd_xVIk?t=11m * cf. Sanskrit tapas, which in Finnish would be an imperative kill (him/her/it)
