"Awake, Awake to Love and Work, the Lark is in the Sky ..."
Possibly my favorite hymn (or the only one I liked) sung at morning "Prayers," Nightingale-Bamford School, NY NY in the late 70's. Some of you may know of that institution of college preparedness from the recent tv series "Gossip Girls" written by another alum considerably younger than I am.

But it's actually a lovely tune, just not when rendered by the ice cream truck's audio?

aka "Morning Song"
