Dave Parlato was a member of The Mothers Wazoo incarnation - tho' did not appear on the recordings at that time. However, during the Petit tour, at one point (on a bus ride to the gig(?), Parlato noticed from the window at a stop a dog urinating in the snow; to which he responded "Don't eat the yellow snow!". According to Dave, "a few days later, Frank had turned it into a song". Dave Parlato provided bass for Zoot Allures, Studio Tan, Sleep Dirt, Orchestral Favorites, Tinseltown Rebellion, Läther, Frank Zappa Plays The Music Of Frank Zappa, Quaudiophiliac, Imaginary Diseases and Wazoo.
In 2006 he was teaching Upright Bass at Robertson's Violins in Albuquerque New Mexico.
He played with Gabor Szabo mid 1970's.
