"Lost in Love" is a 1980 song recorded by the Australian soft rock group Air Supply. The song was written by group member Graham Russell. The original version of the song appeared on theLife Support album in 1979 and was released as a single in Australia, reaching #13 on the Kent Music Report. The group re-recorded the song for the album Lost In Love in 1980 and this version was released as a single in the US reaching #3 on the Billboard Hot 100.
Air Supply's popularity in their native country during the mid to late 1970s had not been matched elsewhere. Russell travelled to England in 1979, and while there, discovered that the group's Australian record label Big Time Records had sold "Lost in Love" to Arista Records in the United States for distribution. Soon thereafter, their song became a hit on the music charts in the U.S. The song spent four weeks at number three on the Billboard Hot 100 chart in May 1980 and topped the Billboard adult contemporary chart for six weeks that same year.
A country music version of "Lost in Love" was recorded later in 1980 by singers Dickey Lee and Kathy Burdick. This version peaked at number 30 on the Billboard country music chart. In 1980, Demis Roussos included it as a duet withFlorence Warner on his album Man of the World. In 1998, it was covered by Kiwi pop group, Deep Obsession, and became a number-one hit in New Zealand. In 1980, Czech singers Lenka Filipová a Karel Zich made a cover named Mosty (Bridges).
