Dizzy Birthday

"Birthday' is a good old rocker on the White Album. It sort of evolved in the studio, with all four fabs contibuting their stuff. Was it the last track that was really a team effort by the Beatles ?Birthday is a rather simple song, but where are its roots, where did they find their inspiration ? In their childhood of course, when they played only rock and roll; Dizyy Miss Lizzy was a crowd pleaser for them, with John exploiting the sawdust in his voice.Put next to each other, Birthday and Dizzy Miss Lizzy show striking similarities: played in the same key, same tempo, and - of course- chord structure. Naturally, they mash well, giving a new life to good old Lizzy's Birthday.
