Israeli Dance Hava Nagila

Here's some information about this song and dance from http://en.wikipedia.org/wiki/Hava_Nagila

"Hava Nagila" is a Hebrew folk song, the title meaning "let us rejoice". It is a song of celebration, especially popular amongst Jewish and Romani communities, and is a staple of band performers at Jewish festivals.

The melody was taken from a Ukrainian folk song from Bukovina.[1] The commonly used text was probably composed by Abraham Zevi (Zvi) Idelsohn[2][3] in 1918 to celebrate the British victory in Palestine during World War I as well as the Balfour Declaration.

The transliteration, spelling of the title and lyrics vary."
