The first releases of this have a blank (smooth) B-Side (i.e. no tone groove). There were only 500 of these original versions pressed. Both sides are labelled "bpm 120 Whitney joins the J.A.Ms" and nothing else. The few DJ copies released have blank labels on the blank side. These original 500 have a "generic" 12" sleeve, some stamped "Made in England".

The versions with the tone grooves (there are two) are reissues. Some labels on the first reissue have "bpm 120 Whitney joins the J.A.Ms" with "Made In Scotland JAMS24T". The second reissue has "Whitney Joins The JAMs" on one side, "120 bpm" on the other. Both reissues come in either a "generic" 12" sleeve, or a plain black sleeve.

All versions were issued in 1987, with the original 500 released on 07-Sep-1987.

A hilarious release from the KLF based on a sample of Isaac Hayes' outrageously funky Theme From Shaft, interspersed with Bill Drummond begging Whitney to join the J.A.M.'s, and Whitney's response lifted from I Wanna Dance With Somebody. An early example of how new technology could allow you to plunder pop's past to make new tunes, before Abba forced KLF to trash their album because of an uncleared sample.
