7D "Bad" singer dies childless, cracking member of the pack (4,2,6) JACK OF SPADES. Can't quite work out the wordplay. I see singer of "Bad" as Michael Jackson. So JACK(less son, childless). Can't work out rest.
I can't see it either but I'll bump it back onto Latest Posts and hopefully one of the experts will see it.
Maybe the singer is JACKO but that still doesn't explain the rest
