In this life I have been hung on by Janis Joplin; smoked dope with the Stones; smorgasborded with Mel Tormé; crashed a $1,000-a-head party with Tony Bennett; was the actress Jane Russell’s dinner escort; been photographed by Jerry Garcia; danced with the MGM star Marge Champion as well as slow-danced with Lana Turner’s infamous daughter Cheryl Crane; shared intimate thoughts about girlfriends with Carlos Santana; and recently listened to Eddie Fisher tell me that Liz Taylor had just called him after decades of silence.

Yes, I’m not the late, great film director. I’m the photographer. I love rock’n’roll, and more than that I love talent. I’ve had this great lifetime capturing it all on film.

I was born in New York City in 1944. Mosholu Parkway was a middle-class neighbourhood in the Bronx. The mother of the actor and director Penny Marshall ran a dancing school in the ballroom of our apartment building. I was drafted in at age 5 to perform there. Ralph Lauren and Calvin Klein attended my elementary and junior high schools, although I couldn’t buddy up with them as they were older.

When the Sixties came along. It was our time and we knew it. Every day something new came: Dylan’s “finger pointing”; the Beatles’ sunshine; then Motown and the Stones. I embraced it all: long hair, billowing habiliments, skinny-dipping.

While all this was going on I had graduated from college. I lucked out when I found the still camera. I soon found my way to Rolling Stone, which had become a hip proving ground. What a trove of coruscating editors, canny wordsmiths, hip secretaries, artists – and the healers and dealers who came along for the ride.

The music was incredible and my camera afforded me access to not only experience all that pleasure but also to capture some amazing moments on film. A very young Tina Turner, still performing with Ike, was blindingly electric, singing and strutting while at the same time dripping sensual ooze. Janis Joplin bearing her soul. Jim Morrison defining what it was to be a rock adonis.

Only once have I been responsible for an iconic image, the subject of which I was clueless to. I had duly covered a concert in which Gram Parsons had performed. He had popularised country rock, which particularly influenced the Rolling Stones. But in 1973, my ex-girlfriend Margaret Fisher, who is still a dear friend, shared a motel room with Parsons and discovered his comatose body the day he died from a heroin overdose. She was so freaked out that she left California for ever. Only years later did I become fascinated with this “fallen angel”. The concert photo I had taken of Gram later became the cover of books and posters, and I never even heard of Gram in the first place.

The scariest day of my life? It had begun benignly at Altamont Speedway in 1969. Along with everyone else, I thought it was going to be Woodstock. I was recruited to “string” for two stock agencies while also slogging for Rolling Stone. The Hells Angels were hired as “security” for $500 in beer. Strange bedfellows to the flower children? Yes, but in those days it was thought as radically chic. Unfortunately, crowd management for 300,000 proved insane for 30 bikers. Over the day the Angels became ferociously unstrung. I unravelled too . . . but for me there was nothing else to do but shake off the paranoia and load film and shoot. You might say that F16 saved my ass.

And the greatest day of my life? Recording Let It Bleed in Hollywood, the Rolling Stones were doing pickups at Elektra. There I was, trying to be cool, but inside there was a 13-year-old jumping up and down and screaming, “Hey, I’m blowing dope with the Rolling Stones!”

So, should we dismiss the 1960s as an irrelevant period in which a group of self-indulgent flower children ran amok? Was it only one huge fantasy camp where our parents said, “OK, it’s 1967. You can go out now but just be back by 1974.”

As a generation, perhaps we were naive in our belief that we were reshaping the world. However, we should honour ourselves for the furtherance of causes and thinking, such as civil rights, dispelling the idea that our nation could draft half a million of its young to fight an unpopular war that its people did not support, furthering the permanent protection of our environment, as well as embracing spiritual and self-growth.

It has been a long, strange trip – one I would never change.
