Item 1:
I was curious to see if any members of LinkedIn had “Sacred Harp” in their profiles. I found over 60 entries, but couldn’t see the names of most of them because they weren’t in my network. Then I checked to see if there was a LinkedIn Group about Sacred Harp. Again, no luck. So I created one — “Sacred Harp Singing“.
Item 2:
In February several members of the Cincinnati Sacred Harp singers supplied the music at my church in Oxford, Ohio. Here are mp3s of the six songs (numbers are the traditional way to refer to the songs in the Sacred Harp song book).

Thanks, nbm. The acoustics in the church are very live, and we deliberately slowed down a bit to make the reverberation work for us.
nice singing! Green Street is a touch slower than we usually do it, but it sounds good there.
