I have given this a little further thought
here are four english songs or melodies or four that are frequently played in english folk clubs, [since no one on mudcat can satisfactorily agree on what a folk song is], that work in standard tuning and which are easy to play the melody and accompaniment, john of dreams, adieu sweet lovely nancy, peggy and the soldier, bonny lass of fyvie o,an american one john hardy.
the following english tunes are straight forward major tunes, jimmy allen, winster gallop,speed the plough,hesleyside reel, random jig, jennylind polka,girl i left behind me,galopede,waters of tyne soldiers joy, just as the tide was flowing, streams of lovely nancy,a fair maid walking in her garden,buttered peas,up and away, the girl with the blue dress on, all of these and many more work perfectly with accompaniment in standard tuning on guitar
