What is Mr Smith doing killing off Pete Seeger [note spelling], please?

Amos's question is of course a most pertinent one. Dealing only with people I have met, let's take as an example Harry Cox. If he wasn't dead, he would be 125 years old. Peter Bellamy, on the other hand, would only be 66, Sandy Denny 63, &c. But Alex Campbell 85. So where did OP envisage the parameters being set?

Has Isla Cameron been mentioned? Or Dominic Behan?
