The songwriter who accused Mariah Carey of ripping off her festive hit ‘All I Want For Christmas Is You’ from an earlier song he wrote of the same name has voluntarily dismissed his song theft lawsuit.Vince Vance sued Carey in June explaining that he co-wrote a song called ‘All I Want For Christmas Is You’ back in 1989, a version of which was recorded and released, enjoying “extensive airplay”, in 1993. That was the year before Carey released her album ‘Merry Christmas’ on which her much more famous song ‘All I Want For Christmas Is You’ appears.Carey’s hit, Vance argued, was a derivation of his song, but no permission was ever sought to exploit his work in that way, which means his copyright was infringed.
