When I listened to Please Please Me yester-day, I thought the piano part in "Misery" sounded pretty easy to figure out (and it was; it's pretty much just a C major scale, although it doesn't start on C). So I figured that out, and then I got the chords too.
My guitar tone isn't the best here, and I think there's a slight tempo mistake in the second piano phrase, but it's close enough.
