More than 200,000 fans gathered in Mexico City's historic central square, the Zócalo, last Thursday night to see Paul McCartney in concert.

Jimmy Fallon's new album of song parodies, Blow Your Pants Off, will feature guest appearances by Paul McCartney, Eddie Vedder and Bruce Springsteen.

In The Beatles’ catalog, “Hey Bulldog” is a bridge between the psychedelic excesses of 1967 and the rock and roll revivalism they would pursue on the White Album and Let It Be. Written by John Lennon, the song is a straightahead rocker featuring a seductive boogie-style riff and some excellent aggressive lead guitar work.

George Harrison’s withering indictment of Britain’s progressive tax system was chosen to open the Beatles’ most progressive musical effort to date. Opening with a rasping cough and a droll count-in, “Taxman” kicks off Revolver in startling fashion, demonstrating both Harrison’s growing sophistication as a songwriter and Emerick’s budding talent for sculpting guitar tones.
