Concert for Martina and Ján is being postponed to May 18, 2019 Due to the unfavorable weather forecast for Saturday, May 4, Concert for Martina and Ján is being postponed by 2 weeks to Saturday, May 18, 2019. The main program does not change and Gregorovce will see both, Richard Müller with the band, as well as Slovak Chamber Orchestra, on the new date. Gusty winds and raining on the soft surface of the football pitch would complicate the safety during stage construction and other preparation works considerably. According to the latest weather forecast, we would face the bad weather throughout the event itself. We hope to see you at the Concert for Martina and Ján at the football pitch Gregorovce in two weeks, on Saturday, May 18.
