I always kinda felt sorry for Freddie Lennon. I know he was a deadbeat dad, but it does sound like the Stanley family (Mimi especially) did their best to keep him away from John (as a "criminal" and "bad influence" to their middle-class boy). Hell, Mimi pretty much managed to keep Julia away from John for his formative years--so you can imagine that the poverty-row Freddie didn't have much of a chance.
Not, I guess, that he much deserved one.
But the story of him trying to move to Australia (or New Zealand) and making the five-year-old (?) John choose between him and Julia (who later sent him back to Mimi) is simply heart-breaking.
Whenever I think of what John might have become without the Beatles, it's hard not to think of Freddie Lennon on the cover of that single.
