"Eloise" is a song first released in 1968 on the MGM label. It was sung by Barry Ryan, and written by his twin brother Paul Ryan. Running for a little over five minutes, it featured strong orchestration, melodramatic vocals and a brief slow interlude. It sold three million copies worldwide, and reached No. 2 in the UK Singles Chart as published by Record Retailer, but hit No. 1 in the NME and Melody Maker charts. It topped the chart in 17 countries, including Italy where he reached No. 1. Ryan also released an Italian-language version of the song, "Eloise (Versione Italiana)", in 1968.

On the back of the commercial success of the 1985 Phantasmagoria album, the Damned released their cover of the track as a single in 1986. It reached No. 3 in the UK Singles Chart, boosted by two different 12" releases. It was not included on any studio albums, but has since been issued on several Damned compilations.

MCA also issued the single in Germany, Australia, France, Ireland, Italy, Japan, New Zealand and South Africa.
