album. Bonnet lasted just one album with the band: Down to Earth
(1979). He recalls "I Surrender" being the only one they had during the painstaking rehearsals before he was replaced on Difficult to Cure
. "That's the only song we had. So we're sitting around looking at each other and Ritchie [Blackmore] would come in for like half an hour and plonk on his bass pedals or whatever the hell, and then he would go. It was unproductive. The thrill had gone, so to speak.
Bobby Rondinelli [drums] really wanted to fix it and get on with it, but we just didn't gel and nothing was happening, so I went home. I went back to LA and the management called me and said, 'What do you want to do?' I said, 'Well, nothing's happening.'

So he said, 'Do you want to sing the songs you like and have another singer sing the songs you don't like?' I said, 'Well, there's no songs there. And two singers - no, that won't work for me.' So I left the band. That was it." (Here's our full Graham Bonnet interview
