Was it folk? Well, full of folk roots anyway. Remember, My cat Dragged in Through the door One fine morn' Ooooweee my dear Henry Dig the dog that cat dragged in!With five string banjo, Jew's harp, slide whistle and kazoo.
The wonderful thing about these guys was their spirited, eclectic style. They were contemporaries of the early Grateful Dead and other early acid rock groups, but with East Coast roots.
