The original plan was to restore Madonna's vocals to the track for the re-release, but she refused to grant permission, hence Basinger was approached instead.
A full Madonna vocal appears on the two-LP and double-cassette formats of compilation release Now Dance 92, entitled the 12-inch mix.
There are several versions of the 1992 remake: The song's lyrics deal with things that cannot be done (some are outlandish, some can be done, but have a high amount of difficulty).
In 2003, Dutch-German pop singer C. C. Catch released a version of the song that reached number 12 on the Spanish Singles Chart.
