The old hymnals didn't call that metric pattern "Common Meter" for nothing, did they?
8/6/8/6 iambic. Almost the entire Scottish Psalter is set to common meter tunes.
.,,.,.
And think of all the ballads sung in that meter too. So you could sing AG to the tune of Sir Patrick Spens, or The Bitter Withy, or Little Musgrave & Lady Barnard, or........ or any of them to its tune, for that matter.

As I have frequently remarked on this forum, it is only a sort of convention that relates a particular tune to a particular ballad ~~ & then it doesn't always hold permanently: look e.g. how Fause Foudrage has got confused with Willie O Winsbury.
