Help! re One Vision docu

Hey there

Simple question, sorry I am not well-acquainted with the people with whom Queen worked during their careers.

In the 14-day docu about recording One Vision (in the studio), who are the various people in there with Queen? I think I see Jim Hutton sitting quietly and smoking; he never says anything. But then there is the guy with the long hair, slight French accent I think; also another guy who looks a little like a woman lol. Who are these people?

Thanks

Mack, the producer. He is German, actually.

The other guy with glasses? Don't know.

No.

...Jim Beach? Paul prenter?

David Richards...

it ain't David Richards , he's just Mack's assisting engineer. don't know what's his name though...anyway Mack , the other guy and jim hutton are the only one's to be seen there

Thanks!
