I first heard this song nearly 50 years ago, I was hitch hiking from Cardiff to London at the start of a trip that eventually took me to the Greek Islands via Yugoslavia (as it was then). I got a lift in a mini and the driver played Crosby, Stills, Nash & Young’s album Deja Vu on cassette. (I could not imagine anything cooler than having a mini with a cassette player!) All these years on we have two cats in our yard and I whistle the melody of CSN&Y’s song every day…
