Title says it all.
Blessed Cecilia, appear in visions
To all musicians, appear and inspire:
Translated Daughter, come down and startle
Composing mortals with immortal fire.
- W. H. Auden
To all who haven’t heard it, I recommend Britten’s setting of that poem. It’s really pretty cool (but not easy to sing).
I got a better one…
I still maintain that the song is about inspiration, and only the more cynical among us think it’s about sex. 
Beat to it by Galena!
Cecilia, I’m down on my knees
I’m begging you please to come home
Cecilia…the sun!
We sang for Saint Caecilia’s feast day at mass this morning.
My choir is scheduled to perform that work on 22 November next year.
