First recorded by Isley-Jaspar-Isley (US #51/R&B #1/NETH #21 1985).
Other hit version by The Housemartins (UK #1/IRE #1/AUS #7/NETH #3/SWE #1 1986).
From the wiki: “‘Caravan of Love’ was a 1985 R&B hit written and originally recorded by Isley-Jasper-Isley for their 3+3 album. The song became the trio’s biggest hit, going to #1 on the Billboard R&B singles chart and #51 on the Billboard pop chart in 1985, but would be their only prominent hit before they splintered into solo careers in 1988.
“British indie band The Housemartins released ‘Caravan of Love’ in November 1986. The a cappella song was a huge success in Europe, reaching #1 on the UK Singles chart on 16 December 1986, (only the second a cappella recording to do so, after ‘Only You’ by the Flying Pickets in 1983), before being denied the Christmas #1 single slotting by a posthumous re-release of Jackie Wilson’s ‘Reet Petite’. The Housemartins’ version also topped charts in Ireland and Sweden.”
