Harrison was a pro at orchestrating complex melodies. I think he's a legend. But I don't think there's any question that he bite that 60's ronie mack single. personally I think it was Phil Spector that goaded him into My Sweet Lord. 60's pop was his specialty and he knew it was going to sell. Spector was a lunatic too so there could have also been some behind the scenes situation between him and Harrison when they produced that song.

But I in no way want to shit on George Harrison though. I think he's one of the best songwriters of his era. I just wanted to point out that My Sweet Lord was like a sample.
