Sure, Charley, the camera lies all the time; sometimes it makes people look better than they do in person too! But yes, many people's smiles when they are singing tend to be fleeting, and the baseline expression serious with concentration, so I have often had the experience of watching someone I know smiles and never catching a smile.
Judy, Jerry wrote the words to "No Consolation" after Stan died (can it really be over a decade ago?) and sang it at the memorial service for Stan at the Seaport the first festival after. It is set to a modification of "Leave Her, Johnny," an eminently suitable choice of melody, not only as a farewell shanty but as the song Stan sang to close the Festival at Mystic for many years. In a way, the closing at
Mystic contains two songs in memory, as Don started singing "Maui"
in his memory since he sang it so often himself.
I do not know if he has sung it much since. The chorus goes,
    It is no consolation,
    To know that time must fly.
    It's still very hard, when the hour comes,
    To have to say good-bye.
I believe I do have all the words around somewhere, or you might PM Jerry (or I can) and ask if he wishes to post them or to supply them individually.
