Former Ozzy Osbourne bassist Bob Daisley is suing the rock star for unpaid royalties. Daisley filed a claim against Osbourne and his company Blizzard Music Ltd. seeking $2 million for unpaid royalties from the 1980 hit “Crazy Train.” While Daisley is in fact credited as a songwriter on the track alongside guitarist Randy Rhoads, his lawyer claims that Osbourne “was benefiting from the songs co-authored by our client, and the audit shows that he was systematically short-changing Mr. Daisley,” and that Daisley had “no choice” but to bring about the lawsuit.

Ozzy’s camp has now released this exasperated statement in response:

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.

Both parties have been going back and forth with this for 36 years, so it seems there won’t be any ending soon. And of course Osbourne may have more pressing concerns.
