Magneto and Titanium Man
Mark Evanier's Kirby: King of Comics holds a slew of cool anecdotes between its covers. One of the coolest tells of a day in 1975 when Paul McCartney met Jack Kirby. At the time, Paul was touring with his band, Wings, promoting the release of their new album that included "Magneto and Titanium Man," a song boasting the influence of three Marvel super-villains. During a concert at Southern California's Forum Theater, Kirby, who had been invited by Paul's record company, presented the ex-Beatle with a pencil illustration that showed Paul and his wife, Linda, under the control of Magneto. During the concert, Paul would later introduce and dedicate his song to Kirby–all to the thunderous applause of the audience.
