1980-05-27 - In Paris France, The Clash played a show in which harmonica player Lew Lewis guested on three songs - White Man in Hammersmith Palais, Train in Vain, in Jimmy Jazz as featured here. He later played on the Sandinista tracks "Version City" and "Look Here."
This is the only time they ever played with a harmonica player live and I think it adds a good touch to all three songs.
