Interesting-

I tend not to be too concerned with origins but with song content, context of singing- purpose etc and type of transaction- that is either begging or offering or if the bowl contained liquids which sometimes it never did. It is important to discover if the song was actually used in visitation or celebration that is door to door or in the hall or simply offered for performance - whilst sitting around, on the stage that is not part of a wider ritual activity.
