Question:
Bruce Lee was born on November 27, 1940, at the Chinese Hospital, in San Francisco's Chinatown. According to the Chinese zodiac, Lee was born in both the hour and the year of the Dragon, which according to tradition is a strong and fortuitous omen. Lee and his parents returned to Hong Kong when he was three months old. Bruce's father, Lee Hoi-chuen, (Li Hai Quan ) was Han Chinese, and his mother, Grace Ho (He Ai Yu ), was of Eurasian ancestry.
At the invitation of Ed Parker, Lee appeared in the 1964 Long Beach International Karate Championships and performed repetitions of two-finger push-ups (using the thumb and the index finger of one hand) with feet at approximately shoulder-width apart. In the same Long Beach event he also performed the "One inch punch." Lee stood upright, his right foot forward with knees bent slightly, in front of a standing, stationary partner. Lee's right arm was partly extended and his right fist approximately one inch (2.5 cm) away from the partner's chest. Without retracting his right arm, Lee then forcibly delivered the punch to his partner while largely maintaining his posture, sending the partner backwards and falling into a chair said to be placed behind the partner to prevent injury, though his partner's momentum soon caused him to fall to the floor. His volunteer was Bob Baker of Stockton, California. "I told Bruce not to do this type of demonstration again", Baker recalled. "When he punched me that last time, I had to stay home from work because the pain in my chest was unbearable". It was at the 1964 championships that Lee first met Taekwondo master Jhoon Goo Rhee. The two developed a friendship - a relationship from which they benefited as martial artists. Rhee taught Lee the side kick in detail, and Lee taught Rhee the "non-telegraphic" punch. Lee appeared at the 1967 Long Beach International Karate Championships and performed various demonstrations, including the famous "unstoppable punch" against USKA world Karate champion Vic Moore. Lee allegedly told Moore that he was going to throw a straight punch to the face, and all he had to do was to try to block it. Lee took several steps back and asked if Moore was ready. When Moore nodded in affirmation, Lee glided towards him until he was within striking range. He then threw a straight punch directly at Moore's face, and stopped before impact. In eight attempts, Moore failed to block any of the punches. However, Moore and grandmaster Steve Mohammed claim that Lee had first told Moore that he was going to throw a straight punch to the body, which Moore blocked. Lee attempted another punch, and Moore blocked it as well. The third punch, which Lee threw to Moore's face, did not come nearly within striking distance. Moore claims that Lee never successfully struck Moore but Moore was able to strike Lee after trying on his own; Moore further claims that Bruce Lee said he was the fastest American he's ever seen and that Lee's media crew repeatedly played the one punch towards Moore's face that did not come within striking range, allegedly in an attempt to preserve Lee's superstar image. However, when viewing the video of the demonstration, it is clear that Mohammed and especially Moore were erroneous in their claims.

Answer the question at the end by quoting:

Cream were a 1960s British rock power trio consisting of drummer Ginger Baker, guitarist/singer Eric Clapton and lead singer/bassist Jack Bruce. The group's third album, Wheels of Fire (1968), was the world's first platinum-selling double album. The band is widely regarded as the world's first successful supergroup. In their career, they sold more than 15 million copies of their albums worldwide.
In 1968 came the band's third release, Wheels of Fire, which topped the American charts. Still a relative novelty, the "double album" of two LP discs was well suited to extended solos. Wheels of Fire studio recordings showcased the band moving slightly away from the blues and more towards a semi-progressive rock style highlighted by odd time signatures and various orchestral instruments. However, the band did record Howlin' Wolf's "Sitting on Top of the World" and Albert King's "Born Under a Bad Sign". According to a BBC interview with Clapton, the record company, also handling Albert King, asked the band to cover "Born Under a Bad Sign", which became a popular track off the record. The opening song, "White Room", became a radio staple. Another song, "Politician", was written by the band while waiting to perform live at the BBC. The album's second disc featured three live recordings from the Winterland Ballroom and one from the Fillmore. Clapton's second solo from "Crossroads" has made it to the top 20 in multiple "greatest guitar solo" lists. After the completion of Wheels of Fire in mid-1968, the band members had had enough and wanted to go their separate ways. Baker stated in a 2006 interview with Music Mart magazine, "It just got to the point where Eric said to me: 'I've had enough of this,' and I said so have I. I couldn't stand it. The last year with Cream was just agony. It damaged my hearing permanently, and today I've still got a hearing problem because of the sheer volume throughout the last year of Cream. But it didn't start off like that. In 1966, it was great. It was really a wonderful experience musically, and it just went into the realms of stupidity." Bruce and Baker's combustible relationship proved even worse as a result of the strain put upon the band by non-stop touring, forcing Clapton to play the perpetual role of peacekeeper. Clapton had also become interested in the music of Bob Dylan's former backing group, now known as the Band, and their debut album, Music from Big Pink, which proved to be a welcome breath of fresh air, to Clapton, in comparison to the incense and psychedelia that had defined Cream. Furthermore, he had read a scathing Cream review in Rolling Stone, a publication he had much admired, in which the reviewer, Jon Landau, called him a "master of the blues cliche." In the wake of that article, Clapton wanted to end Cream and pursue a different musical direction. At the beginning of their farewell tour on 4 October 1968, in Oakland, California, nearly the entire set consisted of songs from Wheels of Fire: "White Room", "Politician", "Crossroads", "Spoonful", "Deserted Cities of the Heart", and "Passing the Time" taking the place of "Toad" for a drum solo. "Passing the Time" and "Deserted Cities" were quickly removed from the setlist and replaced by "Sitting on Top of the World" and "Toad".

Why did they breakup?
