The Baal Shem Tov, or Besht —  the founder of Chasidism — 
met the soul of the Messiah during an ascent to heaven. 
The Besht asked him, "When will the Master come?" 
The Messiah answered, "When your wellsprings break forth to the outside!" 
(from a letter written by the Besht to his brother-in-law about one of his soul ascents) 

Shoshanat Yaakov

PURIM SAMEACH!

Shoshanat Yaakov is printed at the end of most Purim booklets (the kind people use to follow along with the megillah reading of Esther). Traditionally people launch right into Shoshanat Yaakov immediately after the brakhah that follows the megillah.

Listen to a version of Shoshanat Yaakov on B'nai Jeshurun's website

Listen to the version Reb Duvid knows
(recorded on an iPhone because my iRiver isn't working – sorry for the lower quality)

It's obvious that the first version is Chasidic but I don't know the lineage of either of these melodies.

If you look over the words below, you'll see that Shoshanat Yaakov is a substantial rewrite of the theology of the book of Esther, inserting a divine "Thou" where Mordechai, the most pious figure of the story, doesn't even come closer to recognizing God's presence than saying to Esther, "If you fall silent, help will come from another place." (Of course according to Chasidus, the divine presence is symbolized by Vashti and then Esther—which is another way of placing God into the story.)

In a shul where everyone knows the song and breaks out singing right at the end, Shoshanat Yaakov has another function: to firmly place the phrase "Cursed be Haman, Blessed be Mordechai" in everyone's mind, installing a never-ending melody-loop—thereby making it even more challenging to reach the state called "Ad delo yada", where one doesn't know the difference between "Cursed be Haman" and "Blessed be Mordechai".

Transliteration and translation:

Shoshanat Yaakov, tzahala v’samechah bir’otam yachad t’khelet Mordechai!

Arur Haman asher bikesh l’abdi, barukh Mordechai haYehudi.
Arura Zeresh, eshet mafchidi, berukhah Eshter ba’adi.
Arurim kol har’sha’im, berukhim kol hatzadikim
vegam Charvonah zachur latov.

O Rose of Jacob, exulted and joyous, upon seeing Mordechai’s royal blue!

You were their salvation forever, their hope in each generation,
to make known that all who hope in You will not be put to shame,
nor will they be disgraced forever, all who trust in You.

Cursed be Haman who sought to destroy me; blessed be Mordechai the Jew.
Cursed be Zeresh the wife of the one who terrified me; blessed be Esther for my sake.
Cursed be all the wicked; blessed be all the righteous;
and may Charvonah also be remembered for good.

You can see the words in Hebrew here, and also listen to another Chasidic version sung by Lubavitchers.
