More from the Gab Four!    Lonnie, Jon, Martin and I wander from Revolver through the Beatles era, passing by landmarks including "Teddy Boy", "Ms. L.", "Goodnight Vienna", "Lavatory Lil", Mr. Double-It-Up", and the "Dark Sweet Lady".    Stories and characters you know and love, and maybe some you should discover!    Who doesn't want two girls [or young men] in the back, calling them Daddy?
