Lord" in Indian religions – from "Om Christ!" and Krishna, to Buddha and Allah – with varying degrees of success. Backed by a band that again included Billy Preston, Harrison turned "My Sweet Lord" into an extended gospel-funk piece, closer in its arrangement to Preston's Encouraging Words version and lasting up to ten minutes. Harrison's second and final solo tour took place in Japan in December 1991, with Clapton's band. A live version of "My Sweet Lord" recorded at the Tokyo Dome, on 14 December, was released the following year on the Live in Japan album. Cover versions and tributes "My Sweet Lord" attracted many cover versions in the early 1970s and was the most performed song of 1971. Its coinciding with a trend for spirituality in rock music ensured it was frequently performed on religious-themed television shows. The song was also popular among supper club performers following recordings by artists such as Johnny Mathis. The song was accepted as an authentic work in the gospel tradition; in music journalist Chris Ingham's description, it became a "genuine gospel classic". Many of the Christian cover artists have omitted the mantra lyrics on religious grounds. In 1972, Nina Simone released an 18-minute gospel reworking of "My Sweet Lord", performed live at Fort Dix before a group of African-American soldiers. It served as an anti-Vietnam War statement and the centrepiece of her album Emergency Ward!, which also included an 11-minute version of Harrison's "Isn't It a Pity". Simone interspersed the song with the David Nelson poem "Today Is a Killer", giving the performance an apocalyptic ending. By the late 1970s, "My Sweet Lord" was the most covered song written and released by any of the former Beatles since the band's break-up. Edwin Starr and Byron Lee and the Dragonaires were among the other artists who recorded it. In April 2002, Elton John, Sting, James Taylor, Ravi Shankar, Anoushka Shankar and others performed "My Sweet Lord" to close the Harrison-tribute opening portion of the Rock for the Rainforest benefit concert, held at Carnegie Hall in New York City. At the Concert for George on 29 November 2002, it was performed by Billy Preston.
