"I Don't Know Anybody Else" is a 1989 song recorded by the Italo-house music band Black Box. It was the second single from their début album Dreamland and was released in the first months of 1990 in most countries worldwide.
The song had a great success including the Irish, Swiss, Norwegian and UK Charts where it reached the top five. In other countries, the single peaked between number 5 and number 10. The song entered the UK Charts on 17 February 1990 and remained for eight weeks.
The song features an uncredited Martha Wash on lead vocals. Wash later sued the record label for royalties and directly contributed to legislation ensuring proper credit for vocalists on both songs and music videos.
"I Don't Know Anybody Else" is a misinterpreted lyric from "Love Sensation" by Loleatta Holloway, where she sings "I Don't Love Nobody Else" in the second verse in the exact key and melody as the hook of "I Don't Know Anybody Else".
