I'm the guy in the brown t-shirt under the "tenor"-labeled roof support, the one with a whitish cow on his back...
The first video is 213 THE GOOD OLD WAY, don't know the leader's name but I think I should, Bruce Rowland maybe? The second is 35 SAINTS BOUND FOR HEAVEN vv. 1 & 3; don't know her name either. The third is 309 LIVING LAMB, vv. 1 & 3, led by Bob Schinske. Thanks to Wing L. Mui for posting the videos! (All references are to the 1991 edition of The Sacred Harp (Denson).)
