The intro was only on the American release, I believe. It's also available in the Capitol Albums box set version on CD, if you're willing to pay for that.
And "Help!" pretty much WAS a self-analysis therapy session. The Beatles had nothing to do with the creation of that intro, so far as I'm aware. The American version only had the music from the film, including the instrumental incidental music. This is what you get on The Capitol Albums. I believe A Hard Day's Night is the same way, also on the Capitol Albums set. I don't own the sets though, so I'm not sure.
