Sabbath had become too confusing for people—how many lineup changes can a fan put up with? One minute Ronnie was lead singer, then it was Ian Gillan, then it was Glenn Hughes, then it was Tony Martin, then it was Ronnie again, then Tony Martin was back in. Fans didn’t know if they were coming or going. If a band sticks with the original lineup, maybe with the occasional tweak, fans will stay loyal. But if they don’t know who is or isn’t in the band, they’re far less likely to buy the band’s latest record. My loyalty to Sabbath was being tested to its limits, so I knew exactly how they felt.
