Chodesh tov -- happy new month of Adar!
This is the month of which our sages said, "When Adar enters, joy increases." In light of that, here's a setting of the c. 11th century hymn "Adon Olam," which is part of traditional daily prayer and which we sing at my shul every single Shabbat, set to the melody of Pharrell Williams' 2014 hit "Happy."
(Speaking of which -- if you missed Ethan's piece in The Atlantic last year, YouTube Parody as Politics: How The World Made Pharrell Cry, it's worth reading. And there are some amazing international "Happy" videos at We Are Happy From -- the one I remember from Madagascar seems to have been taken down, but there's a lovely one from Namibia...)
Here's to Adar and to being happy!
