The history of Gesarol-P. Mobil 1969-2015. If somebody spends more than forty five years under the sign of rock and roll, it’s time to make an account. Let’s see! 1969. On the 20th of august in the Youth Park of Lőrinci, the Haus Byrds played a double show. At the beginning of the second part, the front man of the band made an important statement: “Ladies and gentleman please welcome on the stage: The Gesarol.” It was the official name-giving ceremony of the band.
