Il Volo performed O Sole Mio in ColiseoBalear (also known as Plaza de Toros) in PalmadeMallorca in the Balearic Islands. I think this territory is governed by Spain but I'm slightly confused since the show hosts aren't really speaking in Spanish. In fact, the performance is for a German TV show called "Wetten Dass." Anyway the place is soooooooo cool.
This is Il Volo's 15 minute interview from that show, Wetten Dass. 15 minute interview is pretty cool, except I have no idea what they are saying ;(
