Songwriters sometimes subconsciously copy songs that they had heard a decade ago. In a few widely publicized cases, this has resulted in a lawsuit. In Bright Tunes Music v. Harrisongs Music, 420 F.Supp. 177 (SDNY 1976), Ronald Mack and his publisher successfully sued George Harrison for copying the melody of Mack’s composition “He’s So Fine” into Harrison’s “My Sweet Lord“. This finding was upheld on appeal in 1983 as ABKCO Music v. Harrisongs Music.
