47. X? Band? Song?

This particular place in X city has been an inspiration for a famous song by a very famous band. Later on it became part of the name of the album for that band. For the city X, and esp this place, a particular location related to this place was renamed after the band after a few years of release of the above-mentioned song. Identify X, the band and the song.

Answer: X is Berlin and the place is Berlin Zoologischer Garter railway station. The band is U2 which came up with the song Zoo Station. The Berlin U-Bahn line U2 passes through the station, it was numbered U1 at the time; a rearrangement and renumbering of the line took place in November 1993, when the section linking it to the remainder of the line in former East Berlin was reopened.
