I agree with Hilo and I find these songs are quite entrenched. Our later pub session gets a lot of local younsters in, from teens to 30 somethings, and they seem to know and always respond well to these songs. Country Roads, Leaving On A Jet Plane, The Gambler, You've Got A Friend, Lying Eyes etc etc. I can understand that a folkie might prefer to not hear these but the idea that people are thick if they like them is a wee bit off.
