I expect lyric sheets from amateurs, not from professionals – normal girl or not. Saw Neil Young’s Nashville special last night – no lyric sheets. Also saw some Bob Dylan footage – no lyric sheets. Clapton & Winwood together for the 1st time in 25 years – no lyric sheets. If she doesn’t care enough about the words to remember them, why should anyone else? I’m not tryin’ to start anything, but I think its a valid question.
And to answer your question: If what I wrote, no matter how many years ago, really means something to mean me, then YES, I remember the words. If its something that’s new to me, i.e. I just wrote it, then I practice it until I can perform it in public without a crutch on stage. It not like she’s workin’ 50 – 60 hours as a waitress or pulling 12 hour shifts as a nurse and then getting up on stage. She’s a performer. Learning the words to her own songs is part of her job.
