"…we were invited to the Autumn Festival in Paris and Joan was there, I think she was singing with Philip Glass Ensemble. And I said to the other guys, ‘well if Joan La Barbara’s here, why don’t we include her in our concert.’ So she did…a piece of mine, which she sang against some sine wave oscillators. She did a piece of Bob (Ashley)’s and from then on I think that changed her mind…because she was simply a performer at that time, and then she decided to be a composer too. So I’ve known her for many many years"
