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,[2] 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."[3] 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."[4]
