They include Sammy Hagar's former Justice Brothers bandmate drummer David Lauser, who played on several of Sammy Hagar's solo albums in the eighties before he left for Van Halen and the more recent formation of The Waboritas.

The band also once included keyboardist Jesse Harms, known for appearances on several of Sammy Hagar's previous solo albums as well.

For a mid-2000s live tour after Jesse Harms' departure, the band also included percussionist Gibby Ross, who had also done some studio work on the Livin' It Up!

Sammy Hagar, David Lauser, and Michael Anthony also comprise the harmony-singing rock band Los Tres Gusanos, with whom Vic Johnson often performs as a guest.

However, the Waboritas are still the main musicians on most of the album's tracks with guest appearances similar to the Marching to Mars format.
