The exclusive fan event, on Berlin's U2 subway line, was to promote the band's 'Songs of Experience' album.
Bono and The Edge surprised local fans in Germany Wednesday by giving them a private concert on board Berlin's U2 subway line.
Some 200 fans were on board a private train hired by label Universal Music to an exclusive meet and greet event to promote U2's new album, Songs of Experience. But they weren't told the band's singer and lead guitarist would be among their fellow straphangers. The Irish musicians jumped on board at one of the train's scheduled stops and rode with the group to Deutsche Oper station, where they performed an acoustic set of songs from the new album.
The U2 subway line, short for U-Bahn 2, has been in operation since 1966. U2, the band, also has a history in Berlin. The group recorded their legendary Achtung Baby album in at Hansa Studios near the newly-opened Berlin Wall in October 1990.
