This is Mary Goffeney and here is his website.
Thanks to readers Brian Ford, natalie, JessicaEve and jojo for identifying the guitarist as Mark Goffeney. (The link is to an article about him in Abilities magazine.) And thanks to Moncef Gridda for sending me the first video link. His YouTube clips do not include his name!
