Okay, for You've Got to Hide Your Love Away I picture a dude leaningg his head against a wall (duh)
For Norwegian Wood I see a guy (John Lennon) walking into this girls groovy crash pad that has lava lamps and stuff, with an orange rug to sit on. And at the end of the song, I see an absolutely HUGE housefire with John cackling like mad throwing wood to feed the fire.
For I Want To Hold Your Hand I always picture the Beatles on the Ed Sullivan show.
And, finally, for both Baby's In Black and Twist and Shout I see the Beatles at Shea Stadium.
