In 2003, Daisley filed a lawsuit against the Osbournes, claiming lost royalties for his significant songwriting contributions. Lee claims he was threatened with firing by Osbourne's wife and manager Sharon if he refused to sign a 1983 contract stating that he would relinquish his claims to writing and publishing.
Though officially credited solely to Osbourne, 'Bark at the Moon' was co-written with guitarist Jake E.
