 The piece itself was written during Zappa's recovery from injuries suffered in December 1971, when he was pushed from the stage at London's Rainbow Theatre by a deranged fan.The original piece had lyrics detailing the adventures of a "Man and a dog" (the dog being named, "Rollo") who encounter a couple in some sort of act of lovemaking.The piece was performed with the vocals during much of Zappa's Grand Wazoo Orchestra tour in September 1972.
