Now in its 21st year: moonlighting ghostwriter Ben Thompson shakes up a snowdome of real and imaginary sessions with guests from the far-flung frontiers of musical and literary endeavour. This week's London Ear finds a way through the madness with an imaginary session from The Cosmic Tones Research Trio and music from Pat Thomas to Shirley Crowe.
