The official extended version of the Count Duckula theme, as released on the CD "The Childrens World of T.V. Themes" in 1991. Apparently this disco rendition of the song was recorded in 1988, judging by the copyright information in the album:
"Count Duckula (Disco Version)
Featuring the vocals of Sarah Harding
(Mike Harding) Arranged by Lee Monteverde
