== Cantus What? == 

 The pic of the lady demo-ing bowing reveals a tee bearing the logo "Cantus Delictus," which conjures up a pleasant image of a group of dedicated souls striving to preserve "dead song."  That's much more noble than the tee I sometimes wear to open mikes, which states merely, "Tune It Or Die."  As a devoted folk musician and eager joiner of small, arcane organizations, I would love to find/contact/join said group, if it is a group and not simply a marketing ploy.  Can the poster of the photo shine any light on this?  PS.  I Googled "Cantus Delictus" asking for bread, but was given a stone.  I shall go ask the question on Mudcat.org now.
