This is the fourth entry in the series of hidden tracks. This week focuses in on the unlisted tracks.

There are a number of reasons for issuing a CD with more tracks than are listed on the enclosed artwork and they are as follows:

1. Production time. Simply the artwork is produced before the CD itself is finalized and a few extra tracks are added to the CD at the last minute. This may be the case here as our very own list member Andrew Russ made a request for the tracks off of the difficult to obtain Make Out Club Remix 7" (TB126X) two of which appear on this CD

2. Aesthetics. Quite simply preferring to list 12 tracks rather than 13, to avoid the appearance of a "long-album." This can also happen when the CD contains more tracks than the LP and the artwork for both editions is reproduced exactly as is and enlarged (or reduced) for use on the second format.

3. To hide a cover version. There are a few reasons to hide a cover version but in this case it is likely because the song was simply a throwaway.

Previously unreleased this song is Unrest bassist Bridget Cross playing the opening riff to Styx' "Come Sail Away," from their 1977 album The Grand Illusion.

At about 40 seconds this is the shortest MP3 to have been posted, without including a second track. However, the question of "What is the last track on B.P.M.?" comes up from time to time on the list, and why not answer it again here?
