Apparently on a whim, the band flew to France in 1971 to play at a canceled festival. But they were housed at Château d’Hérouville, a a residential recording studio in Hérouville, France made famous by Elton John, who recorded three albums at their, (Honky Château, Don’t Shoot Me I’m Only The Piano Player and Goodbye Yellowbrick Road).
Lots of other famous people recorded there, including Marc Bolan, Gong, David Bowie, Pink Floyd, Bad Company, Iggy Pop, Fleetwood Mac. It was also also apparently once home to Chopin and Van Gogh. Though the Grateful Dead did not record there, they did end up playing an impromptu show in the in the backyard as documented by this great high quality recording.
