I remember watching Festival Express, a documentary on a train trip some musicians took while travelling round music festivals in Canada a la Woodstock. They would drink, smoke and jam on the train, and get off to perform at festivals again and again. It was a great big party on tracks. Anyway, there was this scene of Janis Joplin performing and she was so alive I thought she would self-combust or burn up the screen at the very least. She was absolutely electrifying and she couldn't even carry a tune properly. She also died 2 months after this train trip. The old lady sitting next to me started sobbing silently as we watched Janis sing her heart out and strangely, I cried too.
