Compare and contrast

1. Faces: I wish that I knew what I know now When I was younger[.]

2. Bob Seger: Wish I didn't know now what I didn't know then[.]

Personally I lean toward Bob. Although both are true.

Nina Simone: Yeah, regrets, I've had a few[.] But then again, who feel to me uncertain. I did what I had to do and saw it through without exemption[.]

Watch the movie and you'll understand the poster.

An aside, but Nina's lyrics don't jibe with my recollection. And many lyrics also don't seem to be what I remember.

Oh well, I sing what I know.
