"Can't Smile Without You" was recorded by Manilow in 1977 and released on his 1978 album, Even Now.
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".
