What a delightful thread, from before my time "around here". I actually sang something in public a few weeks ago, at a local sing-around. I can hardly imagine anyone thanking me for singing - you'd understand if you heard me - but I wanted to share that song so badly at the time that I did it. Some others there were also much more song-writers than vocalists, or I would never have had the nerve. You would thank my wife for singing, though; she does it beautifully.
