BISMARCK, N.D. — North Dakota native Lawrence Welk’s trademark bubbles and music attracted legions of adoring fans and made him millions of dollars.

A North Dakota Historical Society official says the state is trying to channel the “marketing genius” of the late bandleader to boost attendance at his boyhood home, which has lost money since the state purchased it two years ago.

The site opens May 26, and things being planned this season to draw visitors include presenters who will talk about everything from blacksmithing to beer, and perhaps a Woodstock-like “jam session” that could draw accordion players.
