Fact is, if somebody really really loves a certain type of music, they tend to sing more than one song in that genre

If he sang "Wild Mountain Thyme" (ignoring that some of the verses were written by Francis McPeake or that Ed might have tinkered for copyright reasons) would he be a little more Folkie?

Being a singer songwriter is good fair for a Folkie and his Wiki has him doing the Folk circuit at some time. Where did Dylan go when he had done enough Folk?

He loves music & doing spontaneous things for his fans, and charity. It makes him a dude, with a soupcon of Folkie in him. I doubt I would choose to listen to most of his stuff but if I heard him I would not switch off.
