We are already talking about the meaning of "Good on you son" as with the lyrics is easier to do, but with the titles maybe we can dig something before:

I found that trapper has a meaning similar than drug dealer, maybe it's something metaphoric...
2.Back On The Dance Floor

We know this talks about a Liverpool guy that lives in Newcastle, and is a Liverpool FC supporter and miss his city
5.When You Leave
6.Good On You Son
About director Robert Day? Apparently about a British that grew up in a poor enviroment and ends in LA being succesful

According to wikipedia, a Drover's road is " is a route for droving livestock on foot from one place to another, such as to market or between summer and winter pasture (see transhumance).
