This is a great soundtrack from Mark, I would love to watch Mark play Bass, just to see if he approaches it in the same way he does the guitar. It's interesting you mention the Mike Oldfield style thing with Hard Cases and Four in a Row, I can see what you mean, I have said elsewhere they do share a similar style in various ways, and on Mike's Celtic album Voyager, I can hear Mark's Celtic stylings a lot, in fact it could even be a Knopfler soundtrack album, listen to Celtic Rain for example. Voyager even has Liam O'Flynn and Sean Keane playing on it.
