Double Dong
From This Might Be A Wiki
Ghost Krabb, Heaven and Plen-T-Pac were the members of a human beat box band called Double Dong. The band used the kazoo as the lone instrument aside from the human voice. Ghost Krabb, also addressed during the set as MC Ghost Krabb, said very little during his performance, until the time came for him to pontificate on The Importance of Goals.
Double Dong opened up for They Might Be Giants a few times in 1998, including performances in Orlando, FL and Boston, MA. Additionally, they contributed beatboxing and vocals to Mono Puff's Extra Krispy.
