This single is a release from the soundtrack of the Andrew Lloyd Webber musical 'Joseph and the Amazing Technicolor Dreamcoat'. The mega-remix is a medley of different songs from the musical, in true Eighties style (but released in 1991, oddly enough). It actually was a hit in the UK, reaching number 13 in December 1991.
