The Lovin' Spoonful became part of the American response to the British Invasion and was noted for such folk-flavored hits as "Jug Band Music," "Do You Believe in Magic," "Summer in the City," "Daydream," "Nashville Cats," "Did You Ever Have to Make Up Your Mind," "Six O'Clock," "You Didn't Have to Be So Nice," and "Younger Girl."[1] The band, however, began to implode after a 1967 marijuana bust in San Francisco involving Yanovsky, a Canadian citizen. Facing deportation, he gave up the name of his dealer, which caused a fan backlash and internal strife. Neither John Sebastian nor Joe Butler was involved in the matter; neither was even in San Francisco at the time. Yanovsky subsequently left the band and was replaced by Jerry Yester. - Wikipedia
