No one particular song for me. I've loved guitar music (among others, but guitar in particular) for as long as I can remember. I always wanted to play but never got round to it.
Dad gave me a guitar (that I still have, albeit with the living sh!t modded out of it) when I was 14, and some very dry lesson books. I got bored in about 2 weeks.
2 years later, at 1am, both of us drunk, my now-bassist (friend since infant school: we're both 25 now) said he'd started learning to play and picked up the guitar. Mum played as a kid and her old acoustic was lying around as well. I grabbed it.
He taught me Smoke on the Water on the low E, one finger: 0-3-5-0-3-6-5 etc :lol:
That'll do me, I thought :!: I started learning riffs I enjoyed and techniques I liked the sound of and away it went.
