Ozzy Osbourne is being sued by his former songwriting partner Bob Daisley for unpaid royalties, reports NME.com. Daisley's dispute lies with the royalties from the song “Crazy Train”, which was originally released in 1980 and is credited as an Osbourne song. Daisley has a songwriting credit on the song, however, along with the late guitarist Randy Rhoads.

The Australian songwriter has now filed a suit against Osbourne and his company Blizzard Music Limited, seeking $2 million in unpaid royalties, according to documents released after the filing at a court in Nevada yesterday (August 8th).

A statement has been released by Osbourne saying that the lawsuit is “tantamount to harassmen” and he will “vigorously defend these proceedings.” The statement can be read below:

“For the past 36 years Mr. Daisley has been receiving bi-annual royalty statements and checks from Blizzard Music, totaling in the millions of dollars, which have been routinely cashed. Mr. Daisley has audited Blizzard Music accounts over the years using several different auditing firms who found no discrepancies.   He has previously filed lawsuits in the UK and the US and has lost on each occasion.   
 
“We understand that Mr. Daisley is now in retirement and that these funds are his main source of income, so it is his right to be diligent with his money, but after 36 years, this is tantamount to harassment.  We would have hoped that after 36 years that Mr. Daisley would have lost his unhealthy personal obsession and resentment towards Mr. Osbourne's success.  Blizzard Music and Mr. Osbourne plan to vigorously defend these proceedings.”
