I started out with violin in classical music as a child so the first music would be the contents of The Eta Cohen Method, the book my tutor used.

Regarding guitar, I suppose the contents of The Bert Weedon Play with Yourself in a Day book, (Bobby Shafto, When the Saints and the ubiquitous Guitar Boogie Shuffle!

My first get up in a folk club, therefore practice a first song? I knocked up an acoustic version of a rock song I wrote called Concrete Jungle. I don't recall what I followed it with, but I did have a book called Ireland Sings and many of my early traditional songs came from it.
