Despite the equal billing of the 2 titles on sleeve, only Underpass was the hit single.
This version has a long fade in and includes the second verse that starts with Well I used to remember.
There is also an edited version of Underpass with an A2 matrix.

The duration of track B is not printed on the release.
Runouts are etched apart from the CBS Aston Clinton stampers (A appears as the usual partially formed Λ) and ⋅STRAWBERRY⋅ which are stamped (Everything after VS-318-A* / VS-318-B *)
