"Can't Smile Without You" is a song written by Christian Arnold, David Martin, and Geoff Morrow, and recorded by various artists including Barry Manilow and the Carpenters. It was first recorded and released by David Martin as a solo single in 1975. The version recorded by Manilow in 1977 and released in 1978 is the most well-known.
"Can't Smile Without You" was recorded by Manilow in 1977 and released on his 1978 album, Even Now. Manilow also issued the song as a single in 1978 where it reached No. 1 on the Billboard Adult Contemporary chart and No. 3 on the Billboard Hot 100 chart. Manilow's version has slightly different lyrics from the Carpenters' version such as the Carpenters's line "I can't laugh and I can't walk/I'm finding it hard even to talk" which was changed in Manilow's version to "I can't laugh and I can't sing/I'm finding it hard to do anything". The Carpenters remixed the song with additional orchestration for the B-side of the 1977 "Calling Occupants of Interplanetary Craft" single, revising the lyrics to read "I can't laugh and I can't sleep/I don't even talk to people I meet".
