Slapp Happy (also known as Casablanca Moon) is an album by German/British avant-pop group Slapp Happy, recorded at Virgin Records' Manor studios in 1974.
This album was originally recorded in 1973 in Germany under a working title of Casablanca Moon with Faust as Slapp Happy's backing band, but Polydor Germany rejected it. After moving to London and signing with Virgin Records, Slapp Happy re-recorded it (at Virgin's request) and it was released in 1974 as Slapp Happy. Virgin later re-issued the album as Casablanca Moon.
It was not until 1980 that Recommended Records released the original recording (with Faust) as Acnalbasac Noom (the title Casablanca Moon reversed). For a comparison of Slapp Happy and Acnalbasac Noom, see Acnalbasac Noom.
