Musicians and friends bid farewell to Geordie Gude Sunday, playing for hours at the Portuguese American Club in Oak Bluffs. A continuous stream of live music filled the P.A. Club as artists including Willy Mason, Jemima James, Taurus Biskis and members of the Cape Cod group Brothers Rye performed, with Mr. Gude’s West Coast-based brother Padrick Peper playing harmonica.
