I certainly can appreciate people having different tastes in music. So if someone thought the songs from a given early album was boring, one could say that, though I wouldn’t. But by the time they got to Rubber Soul and Revolver, I’m not hearing it.
More sharply, listen to I Want To Hold Your Hand, released on Boxing Day 1963 in the US – though the US doesn’t celebrate the holiday – which truly started Beatlemania in America. Compare it with the single culled from the Sgt. Pepper sessions, Penny Lane and Strawberry Fields Forever, released on February 17, 1967. What a stunning evolution in a little over three years.
On another note, congratulations to Sir Richard Starkey on being knighted.
