Those are great tunes.  I've played them both numerous times.  I especially enjoy playing 'Fly Me To The Moon' because it sits really well on the guitar for chord melody style playing.

GT does not have song lessons on them.  If that's what you mean by given a credit.  I typically do old jazz standards once they are in public domain because then no copyright permission is required to record or teach them.  But those songs won't be in public domain for another couple of decades.

Hope that helps!
