Sorhor,
If you go to our international website and log in to the "Soror Only" link there should be information regarding singing wedding songs for sorors getting married.
or
Check your regional website or call nationals and they can get you the proper materials. I used to have a copy of songs and chants but I loaned it out to some undergrads at home and they never return it.
Enjoy this wonderful "rite of passage" and share some pics of this blessed event.
