From an old postcard:
One of Toronto's happiest nightspots in Flanagan's at the Don Valley Holiday Inn. As Irish a Paddy's Pig and more fun than the Abbey Tavern, Flanagan's swings with lively entertainment in the "come in -join in" tradition.
Irish button boxes are almost always two-row jobs, but they are tuned uniquely. The two rows of notes are tuned a half-tone away from one another so that the instrument becomes a 'sort-of' chromatic box. Other two and three row boxes are tuned in keys a fourth apart...a whole different kettle of fish. Usually Irish players play only the right side.
