My Sweet Lord lawsuit
On February 10th 1971, George Harrison was hit with a lawsuit by Bright Tunes, claiming copyright infringement of the Ronnie Mack song He's So Fine. They contended that Harrison's song My Sweet Lord sounded too similar to He's So Fine. After Harrison listened to the song he realised it sounded very similar to My Sweet Lord in its structure.
Later that year country singer Jody Miller released a cover version of He's So Fine, incorporating the slide-guitar riffs from My Sweet Lord, which made the case against him even stronger.
Harrison was accused of subconsciously copying He's So Fine while writing and recording My Sweet Lord, and forced into a financial settlement. The ruling reportedly shook Harrison's confidence and made him paranoid about writing anything for a time.
