manager and introduced them on stage when they made their crucial appearance at the Monterey Pop Festival in 1967, a performance that marked Joplin's elevation to national prominence. Evolution Bill Graham Presents shows evolved more into high-power, professional lineups of better-known headline bands that made him known as the can-do guy that he was, while Helms, although managing to produce top-flight bands, still showcased bands that tended to be hipper and local. Helms didn't seem to have the need to hire zealous uniformed security guards, so teenagers found it easier to sneak into his dances. Helms ultimately allowed free admission after midnight. The San Francisco Family Dog dances later re-emerged in a new location, the Family Dog on the Great Highway at the edge of the Western World (its exaggerated sometimes heard full title) which opened in the summer of 69.
