As it’s said, A Night At The Opera was the most expensive album ever made in 1975 costing a whooping £40,000 back then.
That's just spiel. There were probably several albums which had been more expensive before that one. Keep in mind that Queen saved fortunes in not hiring session musicians, being their own composers and arrangers, not getting any big-name producers and not having to fly anywhere as they'd just drive between England and Wales.
The reason is because of the number of studios used to record the album.
While they did use quite a few, they weren't by any means the most expensive studios back then. They didn't go to Abbey Road or to the Record Plant in NY or LA (which would've also added flying and taking their equipment there, etc).
Then on the 24th August 1975, Queen make the 40-odd mile journey to Rockfield Studios just outside the town of Monmouth.
Not true. By the 18th of August, they'd already started off three tracks at Rockfield ('Best Friend', 'Fred's Piano Thing' and 'Wreck of the 39'). By the 22nd, they'd already got a rough mix of 'Bo Rhap' (probably under a working title) at The Roundhouse.
So, the whole 24th August date as the beginning of the sessions is completely false.
At Rockfield they mainly work on Bohemian Rhapsody.
Not true. They also worked on ''39', 'Best Friend' and probably many other numbers from the album.
They went back to London and Surrey to finish recording the album.
Just London, not Surrey. But according to the book about Rockfield Studios, they'd be driving back and forth, it wasn't that clear-cut anyway.
They used four London studios
No: they used five.
Sarm East Studios
Back then, they were simply called 'Sarm'.
That's not the name. It was called 'Scorpio'. No 'n'.
Wessex Sound Studios
No. Wessex had been bought by the Chrysalis group and they were undergoing refurbishment. They'd been used in 1974 and would be used again in 1976 and 1977, but not in 1975 as they were temporarily closed for renovations.
Ridge Farm Studios in Surrey.
Back in 1975, the Ridge Farm was just a farm, not a recording studio. It became a recording studio in 1976. Queen used them to rehearse (before the August sessions in Wales), but not to record. All of that has been confirmed to me directly by the CEO of the studios, a decade or so ago.
Have I got all the information above correct?
No, but you're on the right track about some of it.
John hated Hot Space. Frederick's favourite singer was not Paul Rodgers. Rog didn't compose 'Innuendo.' Witness testimonies are often inaccurate. Wales is not in England. 'Bo Rhap' hasn't got 180 vox.
