I discovered this thread while listening to one of the Topic series Voice of the People CD's.
Although a different type of traditional music from that talked about by Rick I can only give his same advice, invest some listening time and your ears will begin to hear the skills of timing and delivery posessed by some of those early singers. Sure there is speed in some of the reels and the jigs but never at the expense of missed notes or ragged timing.
A worthwhile thread Rick, thanks.
