Great to see some sacred cows getting slaughtered here - tho I disagree about Streets Of London - its well-written all round as far as I can see.Sometimes its the fact that you hear so many awful inept renditions.
I do think Ride On deserves a good kicking as well as all these phoney bloody First World War epics,like Willie Mac Bride (someone did a brilliant parody of that one).
Greensleeves is obviously an "art" song that moved into the tradition,but there are some very nice folk versions,including instrumental dance variations.
John Barleycorn is a classic.Anyone who thinks this is the worst folk song ever is beyond help.
