Andre J. Thomas, choral clinician and pedagogue, wanted the 80 or so choir members in an all-day workshop Saturday at First Presbyterian Church to really get to know the song "Keep Your Lamps," a spiritual, before singing it at a concert at 3:30 p.m. today at the church.  So he spoke about his heritage and how he is 86 percent black, according to a recent DNA test, but also a little Irish and 4 percent "other."

"I was worried about 'other,' " he said with a laugh.
