"Crazy" is a song performed by the British R&B girl group Eternal. Written and produced by BeBe Winans, the song is the sixth and final single to be released from their debut album Always & Forever (1993). This was also the only Eternal single to feature all members of the group singing lead vocals, where usually it would only have been lead singer Easther Bennett. The single entered and peaked at number fifteen on the UK Singles Chart, staying inside the charts for seven weeks. This would also be the last single to feature member Louise Redknapp, who left the group to pursue a solo career. It was released shortly after the band failed to crack the American music market with their debut album which was released in March of that year.
