Even before the High Kings’ new album, “Memory Lane,” hit No. 1 on iTunes’ World Chart, Brian Dunphy bubbled with enthusiasm over the reception his band was receiving on its U.S. tour. If the band was surprised that its sophomore album surpassed double platinum status in Ireland, the U.S. success was almost overwhelming.

“We don’t have the rock star kind of crazy fans, but we have very dedicated, loyal fans,” he said from the band’s tour bus as it travelled through upstate New York. “We signed a couple of arms last night and were given a big, massive bowl of rhubarb muffins by another fan. Some of the fans traveled seven hours to see us and then waited in the lobby for four hours because they wanted front-row seats.”
