"I Just Can't Wait" is the debut single by the English singer Mandy Smith, produced by Stock Aitken Waterman (SAW), and was the first release by Pete Waterman's new label, PWL in January 1987. Despite intense publicity in the wake of Smith's relationship with Bill Wyman, the song charted poorly in the UK, a result the producers blamed on the hostility of the British media. It proved, however, to be a substantial hit in a number of European countries. Remixed versions of the song were released in the UK in 1992 and 1995, but did not chart.
