There were two different versions released to radio: the more common mix includes energetic electric guitar performing the solo in the bridge; an alternate, lesser-known mix presents melodic solo piano, performed by Philippe Saisse at the bridge. The edit version was that of the guitar mix, which presented a fade out during the second of the two ending chorus refrains. This mix appears on McKnight's greatest hits album, From There to Here: 1989-2002 without the fade, although the piano solo ending is slightly trimmed. The "piano mix" was used in the official video for "Love is" and also appears on Williams's Greatest Hits: The First Ten Years album.
A reviewer from Music & Media commented "What is love? Find out through this dramatic ballad on the right side of kitsch." Head of music Karsten Bendix at Radio Roskilde/Denmark enthused, "I love those harmonies. There are so many ballads around, but these two people can really sing." Alan Jones from Music Week wrote, "This intense, brooding duet is no award winner, issuing every cliche in the book and then some. But it has a certain insidious quality, and the fact that it is featured on Beverly Hills 90210 may be enough to tip the scales in its favour."
