Flower power, at 50

The first rock musical, HAIR, opened on Broadway in 1968.

It captured the spirit of Hippiedom with the exuberance of protest, inspired lyrics, and the shock value of a nude scene. It ran on Broadway for 4 years, in London for 5, and was adapted into a film by celebrated movie director Milos Forman. A generous cousin gifted me the double album set of the soundtrack, and its songs deeply informed my teenage years.

Ten days ago, I got to see a traveling production of Hair in Munich, and I had this strange sense of traveling into the past to look at the present.

Hair was a protest against the Vietnam war, and the draft; a plea for love, peace, and clean air.

It was a paean to the solidarity of youth, to the joys of sex - of all kinds, and free love.

It was a celebration of drugs.

And, yes, to the freedom to wear your hair long.

In the context of the late 60s, the demands that Hair made of society were truly fringe. And yet, its appeal, which was quite unprecedented, could be seen as a pointer to how widely change was sought.

5 decades later, so much of that change has been wrought, particularly in the US.

Though wars may still rage across the world, annual deaths have trended vastly down since the late 60s, and Max Roser has an amazing set of graphs (https://goo.gl/images/ZtP9wY) to show the changes. And draft, a central theme in Hair, was removed in 1973.

'Free' Love, meaning sex outside of marriage, barely merits mention today; same-sex intercourse, and marriage, have wide-spread acceptance, and increasingly, legal sanction. In June 2016, President Obama dedicated the Stonewall Monument in Greenwich Village, Manhattan, to honor the LGBT rights movement. In November of that year, Kate Brown became the United States' first openly LGBT person elected Governor.

During World War II, smog in Los Angeles was so bad that people suspected a Japanese chemical attack. But the US Congress enacted the Clean Air Act in 1970, and progress has been rapid. California is still vulnerable to forest fires and thermal inversion, but air pollution in the US is not a major public health hazard. Meanwhile, 14 of the world's most polluted cities are in India.

And drugs? 64 % of American citizens support the legalisation of marijuana. In 29 states, you can smoke it for 'medical use'. And legal annual marijuana sales crossed 10 billion dollars in 2017.

Long hair? Man-buns is now a thing.

I don't want to make too much of a point of this, but I was really struck by how the performing arts can anticipate change, and, perhaps, just perhaps, influence it.
