First songs I wanted to play at home as well as in our primary school class band (on plastic whistles called Musettes) were When I Grow Too Old to Dream and Whispering Hope - which are probably not classified as folk. WIGTOTD was the first one I could pick out from memory, I think.On the Celtic harp, it was Si Beag Si Mor, which I later found out was supposed to be the first song that Turlough O'Carolan wrote.
