We do too many obits in OffBeat these days (a function of too many people dying), and it’s lousy to read your mail first thing in the morning and find notices of two more deaths. Today I got the word that E Street Band keyboard player Danny Federici died at age 58 after dealing with melanoma for the last three years, and the Hacienda Brothers’ Chris Gaffney, 58, died from liver cancer. One of my favorite Gaffney moments came when he was last in town with Dave Alvin, and he took a turn at the mic to sing the Invaders’ soul classic “Cowboys to Girls.” Everybody – black and white – stopped to dance, not because the band was soulful, but because he was, albeit in a relaxed, offhanded way.
