In 1996, a documentary was released entitled "The Life and Times of the Red Dog Saloon" (also known as "Rockin' at the Red Dog: The Dawn of Psychedelic Rock"), in which the surviving members of the Charlatans (Ferguson died in 1979 from complications from diabetes) were interviewed about their days at the Red Dog. The following year, the Charlatans rehearsed for a series of secret gigs at the legendary Sweetwater club in Mill Valley, followed by a series of reunion performances at The Fillmore. The latter-day line-up of the band, composed of Hunter, Hicks, Wilhelm, and Olsen, were not heard from again until 2005, when they performed an abbreviated set at a memorial concert for Family Dog founder Chet Helms in Golden Gate Park. The foursome returned to Golden Gate Park on September 2, 2007 performing at the Summer of Love 40th Anniversary concert (the show also featured a set from Dan Hicks & His Hot Licks).
