Ron,

I may be wrong, but if I remember correctly, what Natalie Cole did was just add her voclas to the existing song done by her dad. It was probably remixed, but his vocals weren't messed with (at least I couldn't tell the difference from the original). If someone else, say myself, chose to sing a duet with Bing Crosby, as long as I didn't change his voice, I don't see the harm in it. Of course, it would still be an issue as to whether you should do anything with the work of a dead artist. I don't know, but I would assume that Nat King Cole would like what his daughter did.

To me it's the modifying of a performance that bothers me - and this may be a fine line that 10 of us would draw in a different place.
