Ostara is the Germanic goddess of spring. The first part of this chant can be sung as a round, then all sing the chorus together. Or sing it straight, as in the recording below.
Here’s Pamela singing it on March 19, 2011, with a live audience – some of whom are singing along.
Here is another recording, in which Pamela is teaching the song to a group. Sing along and you’ll learn it with them in no time!
