Well spotted E-Z...yes...Ron had a cracking studio at the Wick...kitted out...64 track i think.
Ron and Ian McClagan had been working on It's Only Rock'n'Roll..Keith chimed in..he loved the riff. Then Mick got a whisper...and it's all musical ******' chairs- Ron gets I Can Feel The Fire...and Rock 'n' Roll heads off to Munich -where presumably Keith does 6 squillion overdubs..buries Bowie's bits..and charlie sounds like he's tapping coffee cups from Maccy D's.
The most awful mixdown ever..the alternative mix by Harwood and Musicland Studios is a lot crisper.
Seems no one questioned Mr Unhealth at that time...especially after giving Managers & Producers the old heave **!
