U2's second concert in Mexico City contained a number of differences to the first show. Stuck In A Moment made its fourth leg debut, taking the main set position typically held by either Miracle Drug or Original Of The Species. The latter song was eventually played, appearing in the encore - a place it has not appeared since 8 October 2005. Mysterious Ways was also moved back to the encore, with the Achtung Baby trilogy of Zoo Station, The Fly, and Mysterious Ways finally coming back after an absence of over half a year (the three songs were last played consecutively on 25 June 2005). The big surprise of the night was a performance of Fast Cars to open the second encore. Although it was last played relatively recently on 4 December 2005, this is only its fifteenth performance ever.
