The thing I remember most about this series was the fact that George's speaking voice sounded exactly like Frankenberry's, from the Frankenberry/Count Chocula breakfast cereal commercials that were popular at the time...In other words, nothing even remotely resembling the baritone nasal scouse of the real George Harrison. I also seem to recall a couple of occasions where the animators didn't quite get the lead vocalist correct (in one episode, Paul was singing lead on "No Reply"). In spite of all that, the series still managed to be quite entertaining, and was the first place I had ever heard the songs "From Me To You" and "Paperback Writer." I only owned Beatle albums and not singles, and neither of those songs were on any Beatle LPs at the time.
