reminds me of George's infamous 70's lawsuit--the Chiffons claiming that his "My Sweet Lord" was a blatant rip-off of their 60's smash "He's So Fine"... irregardless of that verdict, I don't think Harrison consciously stole this melody. In fact, if you listen closely it's merely derivative. He relates his travails in the exhausting case in the humour-filled, self-penned "This Song" on his 1976 solo album "33 and a Third"
