Of course, it is, jf. And, do you know, when I quickly jotted down the names of French singers that came to my mind, it was "Leo" that I wrote. Why "Jose" popped into my "fingers" rather than the "Leo" that was in my brain, I'll never know. It was the end of a very long day, involving a family gathering I had organised for my mum, and a few hours travelling too, and so on, but that's no excuse.
My mental picture of Leo Ferrer was of a balding head and a shock of grey-white hair framing the sides and back of his head. He also looked a bit like one of the principals of La Mama Troupe, a theatre group in Greenwich Village in the 1960s, but his name eludes me.
