KFRC 610, the RKO Bill Drake "Boss Radio" Top 40 AM station in San Francisco, had significant influence in the music industry among both counterculture and commercial acts. This enabled festival organizer Tom Rounds, KFRC's program director, to present a colorful and eclectic line-up of popular musicians from both in and outside the region. Canned Heat, Dionne Warwick, Every Mother's Son, The Merry-Go-Round, The Mojo Men, P. F. Sloan, The Seeds, Country Joe and the Fish, Captain Beefheart, The Byrds with Hugh Masekela on trumpet, Tim Buckley, The Sparrows, The Grass Roots, The Loading Zone, The 5th Dimension and Jefferson Airplane were among the performers who appeared. The Fantasy Fair was also The Doors' first large show and happened during the rise of the group's first major hit, "Light My Fire", to the top of the charts.
