Who else would have beaten the shit out of each of them to settle arguments, they are a match made in hell.
I do wonder how long Ozzy would have lasted with Sabbath if it wasn't for Sharon, her old man had Sabbath by the short and curlies. Sharon convincing Ozzy to leave probably woke up Sabbath to the shitty dealings they were getting as much as it broke the band. But at time time a lot of bands where getting shafted heavily by managers and labels so who really knows maybe they liked it and they were happy to see Ozzy leave and get shafted and screwed by the same person.
Kerslake is either on death's door or close but not dead yet. These guys all seem to have stories about them being broke. I can see that money paid back then was different to money today and therefore they needed to invest 80's money differently to be living off it now, but I don't think any of these guys gave up paying gigs. They might not have got the big gigs like touring with Ozzy every year etc but they were all still playing and recording so surely they got some money. The gold records thing with Kerslake probably was a bit of good will laced with guilt from Ozzy and Sharon but it does show they can be compassionate when it suits them.
In 2004-05 18 months after Sharon and Ozzy released the two albums with credits on certain songs removed Daisly and Kerslake got together with Steve Morse and an Aussie screamer who could out scream just about any other singer on the planet and created Living Loud. They only did one album that had five originals on it but it also had six Ozzy songs from those first two albums. It was only a project band and Daisly never claimed it was to screw Ozzy for taking his name off the albums 18 month earlier but it kind of was. It's a pity it didn't sell 100 million copies but it was good and they tore the shit out of those songs live, but I didn't hear any reports they didn't get paid for that album and tour
