"North and South of the River"
Christy Moore, Bono and the Edge collaborated on writing the song "North and South of the River". In 1995, Christy Moore recorded the song, and Bono and the Edge recorded backing vocals for the song. This was released as a stand alone single.
In 1996, Christy released his album, Graffiti Tongue which included an acoustic version of "North and South of the River". This version did not contain the backing vocals by Bono and the Edge, and was a much more stripped down version of the song.
The version featuring Bono and the Edge is included on this compilation.
