mmmmmmm until very recently I would have said that song leading was setting a foundation for everyone else "hang" their voices on, last week I found out that the "performance" was just as important. Normally at the Friday night session we would trot out the songs, get big chorus end of...bit thin on the ground last week so I put in a couple of "performances", same old songs, went a storm with the regulars. Now the explanation is up for discussion, might it be that they felt part of a "performance" rather than just singing? Or maybe the dozen or so joining in appreciated the extra effort? I really don't know except that it made a difference.
