Cause a trip to the moon cost too much

I was reading a list of "Things men should do before they die" in some trashy magazine and an idea over took me. Furthermore, because I think somewhere, someone really has a desire to hear Kermit the frog cover James Taylor I have decided to make a CD. No desire to sell or market. Just a thought to record one. Now I gone and stumbled on another problem- What to record? So I would love some input. Any thoughts and suggestions, song ideas would be great.
