I'd choose to let someone else make the decision on my possibly snappy comeback.I'd be in a can marked ReinCarnation Evaporated People and somebody with a proper motive or amount of curiosity could just add water and stir.

That said, the results would come out as someone who knows all the stuff I've accumulated in 60 years of living (Can The Library Of Digress with all my recordings and books be reincarnated too?), but could sing a wider range of it better and play a whole bunch of instruments. I only started actually singing late in life, so this way I could get a head start from an age when the memorization of lyrics came easier. I'd be content to better utilize what I know now better and start a bit earlier, is all.

I'd come out a bit more handsome, too, I suppose.....
