The Waseda University Glee Club performance of a Song of Departure was recorded and can be purchased.
I strongly invite you to read May’s articles about this event on her blog Gabriela Robin.
A CD and DVD are available on the Waseda university glee club website, it’s said that the DVD will not contain the ∀ Gundam song 限りなき旅路 (Kagiri Naki Tabiji [trans: The Endless Journey]), so I think the CD does.
The CD costs ¥3,000 while the DVD costs ¥4,000. The performance is supposed to last 30 minutes.

Piano Inc. published a digest on its soundcloud page:
It makes me think of A Song to Fly songs like The Ship and especially Hallelujah!
On top of that, since July 11, 2013, a 80 page official chorus score is available on the Piano Inc. shop for ¥3,000.
