Yes, it's a sad passing but we'd all be lucky if we'd had as much fun in life as Guy Clark. He and I grew up in Texas, not that many years apart, and so many of his songs could be part of the soundtrack of my life.
"Desperados Waiting For A Train" is an almost perfect description of my time with my grandfather, hanging out in a domino hall when he was assigned to take care of me after my mother passed away when I was three years old. In the song the old men called him 'sidekick.' Their name for me was 'swamper,' which was the oil field designation for the young guy at the bottom of the pecking order who had to do the really dirty, dangerous work.
There's a wonderful documentary of the life of Townes Van Zandt, Guy Clarks' best friend, "Be Here To Love Me" that is mostly about Townes but has a wonderful ending by Guy and Susanna Clark. It's the best record I've ever seen of that moment in time.
