Jim Capaldi started writing this in Morocco, where he was getting ready for a movie with actor Michael J. Pollard that never got made. Said Capaldi: "Pollard and I would sit around writing lyrics all day, talking about Bob Dylan and the Band, thinking up ridiculous plots for the movie. Before I left Morocco, Pollard wrote in my book 'The Low Spark of High Heeled Boys.' For me, it summed him up. He had this tremendous rebel attitude. He walked around in his cowboy boots, his leather jacket. At the time he was a heavy little dude. It seemed to sum up all the people of that generation who were just rebels. The 'Low Spark,' for me, was the spirit, high-spirited. You know, standing on a street corner. The low rider. The 'Low Spark' meaning that strong undercurrent at the street level."
