In fourth grade I played the part of a prince who had to break an evil spell. I needed to sing three hymns to do it. I knew nary a one. My mom gave me the words and music to Abide With Me.The charm worked and the princess awakened!

Abide with me Fast falls the eventide The darkness thickens Lord with me abide! When other helpers fail And comforts flee Help thou the helpless Oh, abide with me.

Maybe there was more to it, but that was enough to rouse the bewitched princess.
