 Mungo Jerry, which evolved from an earlier blues group, Good Earth, was in effect a jug band on their first live performances and recordings, thanks to their use of jug (played by the group's banjo player, Paul King, who left in 1972), and washboard, contributed by regular "extra member" Joe Rush.Jesse Colin Young moved to the West Coast and formed the Youngbloods, whose first hit was "Grizzly Bear," a jug band standard.Another group with jug band roots was the Grateful Dead.
