Ozzy has long said that "Suicide Solution", a song about the dangers of alcoholism, was written as a tribute to former AC/DC vocalist Bon Scott (Bon Scott) who had died an alcohol-related death in 1980. However in 2002, the writer of "Suicide Solution (Ozzy's former bassist and main lyricist, Bob Daisley), revealed that the song actually alluded to Ozzy himself.
His song "Suicide Solution" created controversy when a fan committed suicide. The fan's parents alleged that Ozzy was responsible and sued him. The suit was cleared completely.

Arrested in September 1989 after attempting to strangle wife Sharon Osbourne while drunk. He awoke in jail the next day not knowing why he was there. He and Sharon reconciled in October 1990 after Ozzy endured extensive drug rehabilitation.
The cover of his 1982 live album "Speak of the Devil" was partially censored in some stores. The cover depicted a fanged Ozzy with blood (actually raspberry jelly) oozing from his mouth. The stores put a sticker over his mouth to obscure the "blood". Once Ozzy discovered this, he demanded that the sticker be removed or he would have his record company pull the album from those stores. Not wanting to lose the album sales of an Ozzy Osbourne recording, the stores adhered to Ozzy's wishes.

Black Sabbath's name came from a 1963 film (Black Sabbath (1963)) starring Boris Karloff. Sabbath's early songs reflected the same types of themes that were the centerpiece of those movies. Ozzy later named one of his solo albums "Diary of a Madman", the title (Diary of a Madman (1963)) of a 1963 Vincent Price horror film.
Along with contemporary Alice Cooper, he was one of the first "shock rockers".
Throws a bucket of water on the audience at his concerts.
Resides in Buckinghamshire, England and Los Angeles, California, USA.
On December 8th, 2003 he was seriously injured while riding his ATV quad bike on the grounds of his Buckinghamshire estate in England. The accident occurred while he was taking a day off from his hectic promotional schedule surrounding the UK release of "Changes" - a duet with his daughter Kelly. He broke his collarbone, six ribs and a vertebra in his neck. The injuries were not considered to be life-threatening, though he has undergone some surgery.
His remake with daughter Kelly Osbourne of the Black Sabbath song "Changes" went straight to #1 in the UK when it was released a week after his quad-bike accident.
Reunited with Black Sabbath in 1985 for the Live Aid (1985) festival, and again in November of 1992 for the last night of Ozzy's so-called "final" tour. After the success of this show, the idea of a new Black Sabbath record and full tour was proposed, and the contracts were written up. However, Ozzy decided at the last minute not to sign them. It wasn't until December of 1997 that all four original members reunited again, to perform and record what would become the live album "Reunion".
Before the success of The Osbournes (2002), he was known by most people as "the singer who bites heads off bats". This rumor traces back to one isolated incident. On January 20, 1982, at a concert in Des Moines, a bat wound up on stage, which had either been stuck in the rafters or thrown up there by a crazed fan. Osbourne bit it for a goof, thinking it was a rubber toy. He had to take a week of rabies shots. Despite a $25,000 donation later that year to the SPCA, the bat story grew to be an urban legend of its own, to the point where even numerous unrelated heavy metal bands were commonly accused of ritualistically killing live animals on stage.

His favorite band is The Beatles, who inspired him to become a musician when Beatlemania spread worldwide.
When he started out in music, the demand for rock singers in his hometown of Birmingham was so strong that anyone with their own microphone and PA amplifier could get a paying gig. Osbourne's father paid for the equipment, to spare him having to work a menial job after his failures in school.
