This seems to have been some private party or some other function that Depeche Mode were invited to perform at. No details about the set list are known at this time.
Daryl Bamonte has told Depechemode-live.com in 2018: "I think this was something to do with Sonet, a company which published Vince and Martin['s songs]. The main guy was called Rod Buckle. But I can't remember what it was for."
