I was just settling down to watch the football last night, when the phone rang. I picked up the receiver, but it was one of those – usually incredibly annoying – calls from a gig, where you can just hear a song reverberating around the venue. After a few seconds I could make out a baritone invocation, some ethereal harmonies in the far distance, and a generally spectral air that was uncannily enhanced by the phoneline. Leonard Cohen, singing “Who By Fire” in Manchester, at his first British date for some 15 years.
