Good progression on it's way

Passed by a friend who started learning guitar at 56 which is not an easy task. Now and then we play together and enjoy songs by Dylan , Neil Young, CCR and so on. He just showed me how his 'picking ' technique has improved by playing 'Streets of London ' . I honestly think that people should use the tool of music to bring peace and understanding . Scientists have discovered that singing improves Your health and mood. I imagine gatherings around huge campfires with guitars and singing ...We (i) shall be released . Alas those fires in the world nowadays are symbols of huge suffering .
