<Tr> <Td> "Trip Through Your Wires" (8) </Td> <Td> "One Tree Hill" (9) </Td> <Td> "Exit" (10) </Td> </Tr> <P> "One Tree Hill" is a song by Irish rock band U2 and the ninth track on their 1987 album The Joshua Tree . In March 1988, it was released as the fourth single from the album in New Zealand and Australia, while "In God's Country" was released as the fourth single in North America . The release charted at number one on the New Zealand Singles Chart . </P> <P> The track was written in memory of Greg Carroll, a Māori man the band first met in Auckland during the Unforgettable Fire Tour in 1984 . He became very close friends with lead singer Bono and later served as a roadie for the group . Carroll was killed in July 1986 in a motorcycle accident in Dublin . Following the tangi funeral in New Zealand, Bono wrote the lyrics to "One Tree Hill" in Carroll's memory . The lyrics reflect Bono's thoughts at the tangi and during his first night in New Zealand when Carroll took him up Auckland's One Tree Hill . They also pay homage to Chilean singer - songwriter and activist Víctor Jara . Musically, the song was developed in a jam session with producer Brian Eno . The vocals were recorded in a single take, as Bono felt incapable of singing them a second time . </P> <P> "One Tree Hill" was received favourably by critics, who variously described it as "a soft, haunting benediction", "a remarkable musical centrepiece", and a celebration of life . U2 delayed performing the song on the Joshua Tree Tour in 1987 because of Bono's fears over his emotional state . After its live debut on the tour's third leg and an enthusiastic reaction from audiences, the song was played occasionally for the rest of the tour and semi-regularly during the Lovetown Tour of 1989--1990 . It has appeared only sporadically since then, and most renditions were performed in New Zealand . Performances in November 2010 on the U2 360 ° Tour were dedicated to the miners who died in the Pike River Mine disaster . During the Joshua Tree Tour 2017 to commemorate the 30th anniversary of the album, "One Tree Hill" has been performed at each show . </P>
