Joan Baez arrived alone onto a stage decked with a settee, standard lamp and a side table with flowers. She sat on a stool, picked up her guitar and sang Steve Earle’s song, God is God (I believe in miracles). A tender rendition, by the end of the first verse, the audience was entranced. This voice, that has sung and spoken about peace and love for decades, was about to tell the same tale again, just one more time.
