By Ned Raggett On the face of it, Bargainville is one of those records that explains to much of the rest of the world (without even trying) that Canada's music scene is somehow terminally in major need of help. Trying to blend the Kingston Trio's then three-decades-old sly folk revival humor with the mingled joy and seriousness of the Housemartins -- and then expecting it to fly anywhere else -- is not what could be called the easiest of tasks. It couldn't have been any easier when the band's full debut appeared in 1993 in the States, when the quartet's seemingly giddy chirpiness must have sounded like an alien broadcast in the days of G-funk's ascendance and the Stone Temple Pilots' popularity.
