It is ridiculous how easy it is to learn songs with youtube tutorials these days. When I were a lad, down t'mines, I had to rely on my shitty ear and occasional tips from my neighbor (who had perfect pitch). Tab books were unheard of. When I went to see bands, you could tell all the guitar players in the crowd 'cause they were staring at the guitar players left hand, trying to figure out the fingerings. Once in a while, you'd be able to buy a guitar mag that had tab from a song you actually liked!
Now, it is literally just go to youtube, type song name and 'guitar' and boom, some nerd will walk you through the whole damn thing, as many times as you need. Amazing.
