Yeah, that was it. One wonders in a case like this whether Harrison consciously used the tune of "He's So Fine" or if it was an "ear-worm" floating around in his head (which happens to all of us from time to time) and he used it inadvertantly for "My Sweet Lord," not fully realizing that it came from outside his head instead of inside. Those things happen.

   I recall John Lennon being asked about this in the Playboy interview. He said that George knew what he was doing and could have change a few notes and got away with it but chose not to.
