I do not know any song by that great soul named Tom Waits which doesn't contain some kind of deep sadness. For more, somewhere in my head a lot of John Coltrane's music, is really filled up by sad kind of blues. More and more: Bob Dylan's BALLAD OF HOLLIS BROWN, traditional (?) ST. JAMES INFIRMRY, Sonny Boy Williamson's DECORATION DAY BLUES. I use to sing the Decoration Day Blues at a local weekly jam session, it always works good not only for me, but for the whole audience and staff. Seems like going so down can create a magic climax, it makes you feel better Thinking of the blues has taken me, now, a little more blue than before Cheers
