I remember going to a concert, a few years ago, where a folk singer sang a song with about 60 verses. I remember the words 'tu ra la" being used a lot. Naturally I was bored shitless. Because I was trying to entertain myself while he was singing (you could say that I was trying to do what he was supposed to be doing), I noticed that he was using a thing called a capo.
I thought, "Lazy bugger, why doesn't he just learn to play the guitar properly?"
My advice - if you're thinking of going to a folk music concert, think again.
