The Beatles created over 240 songs, they recorded many singles and albums, made films and TV shows. Thousands of memorable pictures popularized their image. In their evolution from beginners to the leaders of entertainment, they learned from many world cultures, absorbed from various styles, and created their own. Their cross-style compositions covered a range of influences from English folk ballads to Indian raga; absorbing from Johann Sebastian Bach, Ludwig van Beethoven, Pyotr Ilyich Tchaikovsky, Karlheinz Stockhausen, Elvis Presley, Everly Brothers, Little Richard, and others. The songwriting and performing talents of Paul McCartney, John Lennon, George Harrison, and Ringo Starr, fused in the Beatles' music. Lennon and McCartney initiated changes in music publishing industry
by breaking the Tin Pan Alley monopoly of songwriting. Their legacy became possible due to highly professional work by Brian Epstein and George Martin. In 1994 three surviving members reunited and produced Lennon's previously unknown song 'Free as a Bird'. It was preserved by Yoko Ono on a tape recording made by Lennon in 1977. The song was re-arranged and re-mixed with the voices of three surviving members. The Beatles Anthology TV documentary was watched by 420 million people in 1995.
