by I'm From Barcelona.
Although this huge band (30 members) is actually from Sweden.
The second video is Freddie Mercury & Montserrat Caballé singing the song "Barcelona" in the 1989 ceremony that celebrated Barcelona's win for hosting the Olympic games in 92. This is Freddie's last performance (notice the lack of his famous mustache). The song became the Olympic unofficial anthem and I still remember how it played nonstop on TV during that time here in Israel.
5 more days and I'm there!
