Yes, there was a Maurice Plaquet store in Shepherds Bush.
Years ago, I worked at the Marquee Club in Wardour St. It was like the hangout of people in the music business and you can see a band whilst people were networking. Believe me it was the place to be.
The road manager with Soft Machine was short of a few roadies for their gig at the Rainbow Theatre, Finsbury Park which was #1 rock venue in the country at the time
I was recruited, and I in turn asked my mate if he fancied being a roadie for a day. Of course he did do we both did it.
That’s when I first heard of Maurice Plaquet, a lot of the bins (speakers) used by the band was hired from Maurice Plaquet’s company.
