Knockin' on Heaven's Door

In January 1975 Eric Clapton played on Jamaican singer Arthur Louis' recording of ``Knockin' on Heaven's Door'' arranged in a reggae style. Subsequently, Clapton recorded his own reggae-style version of the song which was released in August 1975, two weeks after Louis's version was released as a single in July 1975. Clapton's single peaked at No. 38 in the UK Singles Chart. The single was less successful in the US, only reaching No. 109 in Cash Box. Clapton's 1996 boxed set Crossroads 2: Live in the Seventies features a performance recorded in London in April 1977. The song was also performed during the Journeyman and One More Car, One More Rider world tours in 1990 and 2003. Additionally, the song has been included on several Clapton compilation albums, such as Time Pieces: The Best of Eric Clapton, Backtrackin', The Cream of Clapton and Complete Clapton.
