I think rdabra's point is that
Let It Be...Naked is one of those titles that's notorious for having copy protection built into it, and he was wondering if anyone has been able to rip it.
Now I don't have a copy of this title myself yet, but I have yet to experience a copy-protected disk that couldn't be ripped in some way. If grip (or the underlying cdparanoia) doesn't work, you can probably pull the audio out with mplayer or something. I've also had success before running
isobuster under wine.
cdfs will probably also work if you need a Linux-only solution to do the same thing. You're unlikely to break anything on your system in any case, unlike on Windows.
And be sure to post back with your experiences, as a help to anyone else with the same problem.
