Twist And Shout: The Beatles were sending a message to the young people of America through this song to "take it off." This was a prelude to all the immoral sexual practices that would take place throughout the sixties.
Bread And Butter: I have heard The Newbeats album containing this song. It's actually quite interesting.
Last Kiss: This song contains a couple majorly screwed up ideas about religion.
First, being good doesn't get you into Heaven, a proper relationship with Jesus Christ gets you into Heaven. (See Acts 2 38)
Second, if the main reason you want to go to Heaven is so you can be with your girlfriend again, you won't get in. This is because you weren't serving the Lord for the right reasons.
