I started with chords, including a F barre chord, fingered the 'cheaters' way by only barring the high F and C and not reaching all the way across to the low F. Of course, I didn't know the names of the notes, I just knew how to hold my hand.
The song? Proud Mary, CCR version. How long did it take? 2 months... ugh...
In the meantime, I sort of learned a few other chords, kind of. I wasn't as good as Dan the Man, that's for sure.
