I did a few searches, here what I have gathered :
Of course, based on the photos and the hashtags I directly started to search about the Viking Cruise company, as we all remember the previous performance on the ship Viking "Sea" 2 years ago (read here if needed).
Also, because last Summer we saw that the company announced to support and sponsor the Libera choir (read here).
Then, the context of the mentioned gig looks clear: the ship Viking "Sun" moored this morning in Greenwich, ending a very long cruise of 141 days that started at mid-December in Miami, and ends tomorrow May 5 in London. So quite surely tonight was a gala dinner before the final disembarkation tomorrow morning (read here for details about that long cruise).
Funnily, Libera would almost have also participated in the Christening of this new boat "Sun", the ceremony was held in Shanghai in front of the Bund, at the exact same place Libera were on a boat 5 months ago
(see about that ceremony here).I have not succeeded yet to find any photo of a festive dinner on that Ship toning that would confirm the mentioned gig... but I can see no other context that the one I expose here above, all things matches too well to allow any other explanation.
So let's search and explore the social medias, for sure some happy people will have posted photos, videos or reports of a choir in white robes singing on their ship tonight
