Jazz Bassist Butch Warren's last jam

An upright bass lies on its side in an office at the Manor Care nursing home in Wheaton, waiting for the ailing man in Room 2 to wheel himself down the hall and play "Softly, as in a Morning Sunrise." For nearly half a century, he has been a ghost, a legend, a slender whisper of a man who appeared sporadically at Washington jazz venues, closing his eyes and leaning over his bass, noticeably lifting the level of play, usually without uttering a word.
