"Stars on 45 Medley" was a song issued in 1981 by the studio group Stars on 45. It was originally released as "Stars on 45" by Stars on 45, in the UK, Ireland, Australia and New Zealand the band was credited to 'Starsound' and the medley itself was named "Stars on 45". Its official title in the US (as on the record and in Billboard) where it was credited to 'Stars On 45' (see image to right) was "Medley: Intro / / / / / / / / / / / Stars on 45". It reached #1 in the Netherlands in February 1981, a few months later #2 in the UK and #1 on the Billboard Hot 100 on June 20, 1981. It is (to date) the longest titled song to ever chart in Billboard, and is usually known by the shorter nickname, "Stars on 45 Medley". The reason for the long title was copyright requirements for the use of The Beatles' songs. On the US single, the initial "Stars on 45" intro is omitted on the 45 recording even though "Intro" appears on the title.

The origin of the single is the Netherlands where numerous bootleg disco singles were floating around and Willem van Kooten, the owner of one of the copyrights, decided to make a similar, legitimate record. He found singers who sounded similar to John Lennon and Paul McCartney and decided to make the single focus on The Beatles. The original version was a nine minute forty-five second 12" mix, then a 45 version was also released and the Beatles medley was later extended to a full sixteen-minute album side and appeared on the Stars on 45's first full-length release, Long Play Album(US title: Stars on Long Play, UK title: Stars on 45 - The Album).

The song was also a huge success in the UK where it kicked off a craze for medleys, with a large number of records in the Stars on 45mold reaching the UK Top 40 in 1981.

The album version of the song moved "Venus" and "Sugar Sugar" to Side Two into a different medley, and added several more Beatles songs as well as a 32 second instrumental extract from George Harrison's "My Sweet Lord" and even a fleeting reference to new wave band The Sparks for a total length of about fifteen minutes. The album version was also released as "Long Play Album"; a detailed listing of the source material can be found there.

The success of the single in North America even resulted in Radio Records rush-releasing a second single for the US market. The last four minutes of the album version of the Beatles medley ("Good Day Sunshine"/"My Sweet Lord"/"Here Comes The Sun"/"While My Guitar Gently Weeps"/"Taxman"/"A Hard Day's Night"/"Things We Said Today"/"If I Fell"/"You Can't Do That"/"Please Please Me"/"I Want To Hold Your Hand"/"Stars On 45") was released under the title "Stars On 45 Medley 2" but peaked at #67 on Billboard's Hot 100. The second Beatles medley single was not released in either the Netherlands, the UK or any other parts of the world.

The Beatles medley was remixed and re-released in a house music version in Europe in 1989 under the title "Stars on '89 Remix", then featuring an alternate selection of Beatles tracks taken from the album version of the medley, coupled with a new "Stars on 45" theme called "Rock the House". The single was remixed and reproduced by Danny van Passel and Rutti Kroese and released on the Red Bullet label as a 7", 12" and CD single, all formats backed with an extended version of the "Rock the House" theme.
