Here are some links to my personal favorite fanfic sites.  If you have a great fanfic I'd love to put it up on my site. Also, if you know of any good fics out there---email me!!
**The Back Jigger
(includes George-fic which is slightly harder to find than Paul or John)
**In My Life
In my humble opinion...the best Beatles fic EVER!
**Rooftop Sessions
lots of fun Beatle-fic here
