"radio station KSJO was warning listeners that the acts advertised on the poster for 1969 festival — particularly Led Zeppelin and Jimi Hendrix — were not going to appear, as they were booked elsewhere at the time. (This situation resulted in a lawsuit — paid for by Zeppelin — against the promoter, who retaliated by paying Hendrix $30,000, an unheard of amount at the time, to fly in by Lear Jet and play for half an hour.)"〔(Bob Blodgett versus Aquarian Family Festival, a free concert - SJ Metro )〕
