The death of frontman Bob "The Bear" Hite was a devastating blow that most thought would end the career of Canned Heat; however de la Parra kept the band alive and would lead it back into prosperity over the next few decades. An Australian tour had been set up before The Bear's death and harmonica player Rick Kellogg had joined to finish off the "Kings of the Boogie" album. This incarnation of Canned Heat without Bob Hite was nicknamed the "Mouth Band" by Vestine and was a huge hit in Australia, especially with the biker crowd. Under the management of "The Push", the band toured the States playing biker bars and began work on a video known as ""The Boogie Assault"", starring Canned Heat and various members of the San Francisco chapter of the Hells Angels.
