The original release of the Jackson 5's Greatest Hits LP in 1971 was cause for celebration, as it encapsulated an extraordinary 18-month strings of back-to-back-to-back-back-etc. hits and was itself a hit souvenir of Jacksonmania. It featured eight smash records, led by the group s phenomenal Motown debut, 'I Want You Back,' plus two immensely popular B-sides 'I Found That Girl' and 'Who's Lovin' You' and something new: 'Sugar Daddy,' a just-dropped single which went top 10 pop and no. 3 R&B; it was then not available on any other J5 LP. This LP reissue is something new again: it features the rare quadrophonic mixes, originally released in Japan only in 1975. These mixes used alternate vocals and sometimes emphasized instrumentation not heard in the J5 singles or LP and as a result these versions are much sought-after. As within this edition these mixes are the stereo folds, consumers do *not need a special decoder or four speakers to enjoy the music.
