Which U2 song features B.B. King on guitar and vocals?

“When Love Comes to Town” features B.B. King on guitar and vocals.

The song appeared on U2's 1988 album Rattle and Hum, a project that explored the band's relationship with American blues, gospel, soul, and rock traditions. B.B. King contributed guitar and vocals, making the collaboration one of the album's most identifiable musical moments.

The recording also connected U2 with a major blues figure whose career stretched back to the 1940s. King's expressive guitar style and vocal presence contrasted with U2's arena-rock approach, but the song was arranged as a direct, energetic blues-rock performance rather than an extended instrumental showcase.

U2 and King later performed together during the Lovetown Tour. The collaboration is sometimes mixed up with “Angel of Harlem,” another Rattle and Hum song, which honors Billie Holiday, or with “Love Rescue Me,” whose guest vocal credits are different. “When Love Comes to Town” is the title specifically associated with King's guitar and vocal appearance.
