"Since I was big enough for my fingers to fit on the keys." Again, he laughs: people don't usually ask him that particular question, although it's a perfectly valid one. "I started playing piano when I was four, but my love affair with the saxophone started when I was about eight."

Extending his hand, he nods once. "I'm Gren." He could add a disclaimer about how he doesn't bite, but he's not on the prowl. He's just playing music by the water's edge at night because it's a beautiful and fun thing to do.

"Are you a jazz fan?" He used to say it's what he lives and breathes and he could still say it, he supposes, but it would be a little bit of a lie.
