Очень надо, очень мало времени

That was the best performance I had ever seen.  

I would like to tell about operetta “The Bat” (летучая мышь) composed by Johann Strauss. It is a charming story of love, flirt, humor, joy and intrigues. I saw this operetta in the theater of musical comedy last year. The operetta has three scenes. I highly advise it for everybody. It is a classical operetta, it is known all over the world. It was a colorful performance with great decoration, music, songs, dances. Also I need to say about great theatre staff, the play of artists was excellent, especially their costumes. I enjoyed all time. There were not vacant seats in the hall. To my mind, this operetta will be interesting for everybody.
