Joni Mitchell at the launch of her first album 'Song to a Seagull' at The Revolution Club, Mayfair on 17/9/68. I had just turned 17 and was assisting Doug. We both had Rolleiflex cameras, so some of these frames are by him and some by me. This was the moment I realised I definitely wanted to do this for a living. I'd never heard of Joni, she performed a few songs and I got a free copy of the album. What's not to like?
