The original version of the song was written and recorded by a group named Alias, and was called "More than words can say".
It was then covered by American group Winger who changed the title to "I need you now (more than words can say)" and finally the group Firehouse have been credited with singing it, though I believe that was a one off live recording.

Songwriter and lead vocalist Freddy Curci was presented with the Million-airs award" by BMI for this song (one million air plays) This is the equivalent of 5.7 hours of continuous play or 50,000 broadcast hours.
