Help identifying unknown couple - wedding at Warkworth

[j_mcquillen]

Might be a bit of a long-shot, but I'm wondering whether anyone can help identify the couple in the photo below, which was taken outside the church at Warkworth.

I've been going through old family photos, and this was in the collection. However, nobody in the family has been able to identify the couple. Neither of them resembles anyone in the family that I know, so it may have been friends / acquaintances, or just a "big" wedding at the time.

There was presumably a military connection, given the guard of honour, but there are no other clues on the image.
