Here's McEwens current bio:

Sharkey McEwen (guitars, mandolin, backing vocals), longtime musical partner of Joziah, grew up in L.A. and played the club circuit before coming to New York in the early 90's. His intuitive, evocative playing is a key ingredient of the band's magic. He is in constant demand as a producer and guitarist for other artists.
