Script for "A Hard Day's Night" - This is the original Alun Owen version, so there are some differences from the final draft. One key change is the names of the Beatles Road Managers. Instead of Norm and Shake, we have Nell and Mal.
Magical Mystery Tour Script (MS Word Format) or html version.
Yellow Submarine Script - It is actually a transcript from the final product and it doesn't indicate the names of the characters who are speaking, but it is useful for quick reference.
Interactive Sgt. Pepper Cover - Not as great of an experience for non-members, but you can at least mouse over and get the names of most of the characters. Interestingly, the only Shirley Temple that works is the one you can't recognize.
One of my favorite blogs, Grow A Brain gave a link to a page with 55 Sgt. Pepper Cover Parodies.
Here is a page where you can watch the entire "Son of Dracula" movie starring Harry Nilsson and Ringo Starr.
