Was a drummer before age 20 and never had any interest at all in the guitar. None. One day I was over at a friend's house and he picked up his accoustic and started playing the opening riff to Back in Black, the song of the moment at that time. It was like a lightbulb went on, I thought "that looks fun, I could do that", and had him show me. All of a sudden I was obsessed with the guitar.
