Despite Evergreen head Scott Ginsberg telling "Radio & Records" that KFAC-FM's format would remain in place, industry analysis warned a format change would occur because of the debt incurred in purchasing the station. Speculation began to accelerate when KFAC-FM dropped format in early July—for only a few minutes—to carry part of a Rolling Stones press conference, then Evergreen took responsibility for a cryptic billboard taken on Sunset Boulevard reading, "Pirate Radio, KLSX, KLOS: Get Ready to Move Over and Let the Big Dogs Eat!" Jim de Castro, who was appointed as KFAC's general manager from Evergreen's WLUP (97.9 FM) in Chicago, later admitted he won free use of that billboard for a month as the result of a golf bet. Finally, Evergreen announced the donation of KFAC and KFAC-FM's music library, with roots dating back to the early 1940s and appraised at $1.8 million, to KUSC; Stanford University and the Los Angeles Public Library acquired KFAC's compact disc library, the majority of titles KUSC already held. KUSC was also presented with a $35,000 check and the rights to the KFAC calls, those would later be placed on a KUSC repeater in Santa Barbara.
