Question: Michael David "Mike" McCready (born April 5, 1966) is an American musician who serves as the lead guitarist for the American rock band Pearl Jam. Along with Jeff Ament, Stone Gossard and Eddie Vedder, he is one of the founding members of Pearl Jam. McCready was also a member of the side project bands Flight to Mars, Temple of the Dog, Mad Season and The Rockfords. He is also the proprietor of HockeyTalker Records.

McCready prefers to play "by ear" rather than from a technical standpoint. He stated, "I'm so ignorant of this technical stuff...I'm not into being a tech-head." McCready's guitar style is usually of an aggressive bluesy nature, and was described by Greg Prato of Allmusic as "feel-oriented" and "rootsy." McCready has cited Ace Frehley, BB King, Ronnie Montrose, Alex Lifeson, Muddy Waters, Michael Schenker, Jimi Hendrix, Pete Townshend, David Gilmour, George Harrison, Joe Perry, Stevie Ray Vaughan, Eddie Van Halen, Joe Satriani, Jeff Beck, Brian May, Angus Young, Ritchie Blackmore, Chuck Berry, Eric Clapton, Jimmy Page, Eddie Hazel, UFO, and Randy Rhoads among his influences. When Pearl Jam supported The Rolling Stones in 1997, Vedder made a joke that McCready is such a big fan of the Stones that he would count the number of lines on the band's vinyl records. McCready is known to use a Fender Stratocaster, a Gibson Les Paul, and a Gibson Les Paul Junior. When the band started, Gossard and McCready were clearly designated as rhythm and lead guitarists, respectively. The dynamic began to change when Vedder started to play more rhythm guitar during the Vitalogy era. McCready said in 2006, "Even though there are three guitars, I think there's maybe more room now. Stone will pull back and play a two-note line and Ed will do a power chord thing, and I fit into all that." Of his live performances, McCready has said, "I can kind of get into a meditative state when I'm playing, something I don't get any other way...You might see me staring up in the sky with my eyes closed. I'm not faking it. That just kind of happens." As time has gone on McCready has contributed more to Pearl Jam's songwriting process. McCready's first writing contribution for Pearl Jam was co-writing the music for the B-side "Yellow Ledbetter" (from the "Jeremy" single), which has since become a regular set closing song during Pearl Jam's live concerts. After co-writing material for Vs. and writing the music for the song "Present Tense" from the album No Code, he wrote the music for three of the tracks on the band's 1998 album, Yield, including one of the band's biggest hits, "Given to Fly". All but one ("Force of Nature", from Backspacer) of McCready's sole compositions for Pearl Jam use alternate tunings, such as open G on "Faithfull" (from Yield), a variation of open D on "Given to Fly", and a variation of open G on "Marker in the Sand" (from Pearl Jam). McCready made his first lyrical contribution for the band with the track "Inside Job", which closes the band's 2006 self-titled album. McCready also cites punk rock band Social Distortion as a major influence, claiming to have seen them live over fifteen times. He also states that he wrote the music to Pearl Jam B-side "Down" after seeing them in concert.

Question: Vivien Leigh (born Vivian Mary Hartley, and also known as Lady Olivier after 1947; 5 November 1913 - 8 July 1967) was an English stage and film actress. She won two Academy Awards for Best Actress, for her iconic performances as Scarlett O'Hara in Gone with the Wind (1939) and Blanche DuBois in the film version of A Streetcar Named Desire (1951), a role she had also played on stage in London's West End in 1949. She also won a Tony Award for her work in the Broadway musical version of Tovarich (1963). After completing her drama school education, Leigh appeared in small roles in four films in 1935 and progressed to the role of heroine in Fire Over England (1937).

Laurence Olivier saw Leigh in The Mask of Virtue, and a friendship developed after he congratulated her on her performance. Olivier and Leigh began an affair while acting as lovers in Fire Over England (1937), but Olivier was still married to actress Jill Esmond. During this period, Leigh read the Margaret Mitchell novel Gone with the Wind and instructed her American agent to recommend her to David O. Selznick, who was planning a film version. She remarked to a journalist, "I've cast myself as Scarlett O'Hara", and The Observer film critic C. A. Lejeune recalled a conversation of the same period in which Leigh "stunned us all" with the assertion that Olivier "won't play Rhett Butler, but I shall play Scarlett O'Hara. Wait and see." Despite her relative inexperience, Leigh was chosen to play Ophelia to Olivier's Hamlet in an Old Vic Theatre production staged at Elsinore, Denmark. Olivier later recalled an incident when her mood rapidly changed as she was preparing to go onstage. Without apparent provocation, she began screaming at him before suddenly becoming silent and staring into space. She was able to perform without mishap, and by the following day she had returned to normal with no recollection of the event. It was the first time Olivier witnessed such behaviour from her. They began living together, as their respective spouses had each refused to grant either of them a divorce. Under the moral standards then enforced by the film industry, their relationship had to be kept from public view. Leigh appeared with Robert Taylor, Lionel Barrymore and Maureen O'Sullivan in A Yank at Oxford (1938), which was the first of her films to receive attention in the United States. During production, she developed a reputation for being difficult and unreasonable, partly because she disliked her secondary role but mainly because her petulant antics seemed to be paying dividends. After dealing with the threat of a lawsuit brought over a frivolous incident, Korda, however, instructed her agent to warn her that her option would not be renewed if her behaviour did not improve. Her next role was in Sidewalks of London, also known as St. Martin's Lane (1938), with Charles Laughton. Olivier had been attempting to broaden his film career. He was not well known in the United States despite his success in Britain, and earlier attempts to introduce him to American audiences had failed. Offered the role of Heathcliff in Samuel Goldwyn's production of Wuthering Heights (1939), he travelled to Hollywood, leaving Leigh in London. Goldwyn and the film's director, William Wyler, offered Leigh the secondary role of Isabella, but she refused, preferring the role of Cathy, which went to Merle Oberon.

Using a quote from the above article, answer the following question: How long did this affair last?

They began living together, as their respective spouses had each refused to grant either of them a divorce.
