The 12" single was Prince's first non-album extended version to be released and because it was only ever released in the UK, a near mint 12" (UK Warner Brothers K 17590 T) copy can and has sold for over £100. It includes extended bass and guitar solos, as well as more repeats of the refrain. Listening to the extended version as compared to the album and Japanese 7" track, it appears likely they are in fact edited down. So perhaps it's more accurate to describe the 12" version as the "original", the LP and 7" being the shortened version. "Sexy Dancer" was a popular number performed live, often giving other band members the opportunity to perform instrumental solos.
