What do The Living Daylights & Creepshow 2 have in common? Both of these 1987 films use the same piece of music that was absent from their respective soundtrack / score releases. "Sacred Heart" was a stock piece of music by Christopher Blackwell which was used for both films from production music company Dewolfe.
Library music is often used in film and television when it is quicker or cheaper to use existing music rather than comppose and record new music. Back in the day, the film studios would get sent catalogues of Library music to use in their productions. Once the had selected a suitable piece of music they would then order a master tape from the music company.
The music in this case was the track "Sacred Heart", taken from the library album "See The Day" from back in 1986.
These industry catalogue records were not available for sale to the public, however they can be found easily on the 2nd hand market such as ebay.
