U2 Rehearse Rarities and Play With Jay-Z Ahead of Tour

The gospel-tinged "Scarlet" is from the band's early album October, and has only previously been performed live at a 1981 BBC taping. In Auckland, opener Jay-Z joined the band for a guest rap during "Scarlet," and he also showed up to help U2 with "Sunday Bloody Sunday." "One Tree Hill," from Joshua Tree, is also a rare addition to the band's live set, though its inclusion on this tour is not as surprising when one considers that it was written about Greg Carroll, a New Zealand native and friend of Bono's who died in a motorcycle accident in 1986.

The band have also been preparing a concert version of "Boys Fall from the Sky," one of the songs that Bono and The Edge created for their score to the Broadway musical Spider-Man: Turn Off the Dark, which opened in New York this week. - more on this story
