      The Beatles were the most influential band in pop history. In their 8year, 12album history,

Paul McCartney, John Lennon, George Harrison and Ringo Starr altered (改变) popular culture

dramatically. And it wasn't just the suits and changing lengths of hair the four Liverpool boys wore

that had such an impact, but what they seemed to stand for. The world saw them as the voice of a

new generation, one with a very different attitude to life.

      Their influence was at its height in the 1960s, but their music continues to stir listeners today.

However, up until recently one aspect of the Beatles was struck in Yesterday: The music had never

been remastered (重新灌录). But on September 9 that situation came to an end, with the release

of the entire band's music in a digital makeover. It is probably the biggest reissue (重新发行) in pop

music history, said British newspaper the Financial Times.

     The albums were remastered at Abbey Road Studios in London, the location where the band

produced much of their work. The cover of their last album, Abbey Road of 1969, featured the four

young men striding (大步行走) across a zebra crossing on Abbey Road itself. It is one of the most

famous of all Beatles images.

     Recently, to celebrate the 40th anniversary of the album, hundreds of Beatles lovers gathered there

to show their appreciation.

     Pop groups come and go. The boy band pursued by screaming fans one year will be forgotten

the next. But the Beatles are one of the few groups whose music seems to have endured (持久).

Why? Paul McCartney's biographer Barry Miles has an explanation: "They were the first rock band…

and they just happened to be the best. They were the first band to play stadiums, to have their own

products. They were groundbreaking in every way, " he says.
