The only way I can remember songs is to have a clear visual picture of the storyline in my mind, otherwise I have trouble remembering the order of verses. On my songs, this is seldom a problem because the storyline is firmly planted in my mind. On the guitar, I usually have little problem hearing the changes, as long as I know the starting chord. Often times if I listen to someone else play I recognize the chords without having to look at the player's left hand.

I might search for lyrics on the internet, or listen to a recording of something I want to sing and write down the words.
