As an interesting note, I really enjoyed the “Lip Dub for the independence” which has been certified by the World Records Academy as the World Record of people in a Lip Dub. It gathered 5771 people in Vic, Catalonia to raise awareness that Catalonia is a nation and that its survival is not assured without independence.
According to the definition in Wikipedia a Lip Dub is a video that combines people lip synching to a song that is afterwards edited with the original audio of the song.
This particular one is very sophisticated since it synced
hundreds thousands of people on a single take performing, dancing and singing to a song by “Obrint Pas” and all I have to say is that it’s brilliant, enjoy it.
