Using the two paragraphs below, when was the Ukrainian Chorus Dumka of NY founded, and when did it play in Ukraine for the first time?

Ukrainian Chorus Dumka of New York was founded in 1949 with the goal "to preserve and cultivate the rich musical heritage of Ukraine",[1] both for the church and for secular occasions. In the beginning, the chorus was a men's chorus of Ukrainian immigrants who met to sing music they loved.[1] The first music director was L. Krushelnycky.[2] The group became a mixed choir in 1959.[3] 

They have performed in New York at locations including in Alice Tully Hall, Avery Fisher Hall, Brooklyn Academy of Music, Carnegie Hall, Madison Square Garden,[1] St. Patrick's Cathedral,[2] and Town Hall.[4] They toured to the Kennedy Center in Washington, and in several European capitals. In 1990, the chorus toured Ukraine for the first time,[1] singing in Kyiv, Lviv, Poltava, and Kaniv.[2][3] They made recordings of both church and secular music.[1]
