I'm partial to The Banks of the Sweet Primroses as sung by Phil Tanner. This is tricky, 'cause he was from Wales but didn't apparently consider himself a Welshman. Still, great song and probably English in origin.

Has Solvay survived in oral tradition? Most versions sung today are based on Lloyd re-construction, hence more representative of the revival than of the folk tradition.

I love Spencer the Rover.

I also think The Bonny Bunch of Roses, as it appeared on broadsides, was very English and indeed hegemonically so: "England and Ireland and Scotland, Their unity has never been broke." Ha!
