"The More I See You" is a cover of a song written by Mack Gordon and Harry Warren in 1945, and popularised by Chris Montez in 1966. The track began as an original composition, but McCluskey found himself singing the words to "The More I See You" over the song, which morphed into a cover version.
"The More I See You," initially written as an original composition, became a cover version when McCluskey started singing the lyrics to it.
