As I'm sure you know, back in the 1980s Chrissie Hynde of the Pretenders had a baby with Ray Davies of the Kinks. This was shortly after the Pretenders had covered the Kinks' "Stop Your Sobbing"; I think there was a deal in place whereby if the band covered one of your songs, you then got to impregnate Chrissie.
That little girl, Natalie Rae Hynde, is now 24, and I have seen Internet reports of her studying English literature in London (which sounds plausible) and working as a model (which doesn't). I have not heard, though, about her making any music, which seems a little odd since both her parents are Rock & Roll Hall of Famers, and real ones, not like Lloyd Price or the drummer for the Rascals or anything. The bloodlines don't get much better than that.
How many other kids can say they are the child of two members of the Rock & Roll Hall of Fame? I found four others:
Ronnie Turner (son of Ike and Tina)
China Kantner (daughter of Paul Kantner and Grace Slick)
Chynna Phillips (daughter of Michelle and John Phillips)
Rhonda Ross Kendrick (daughter of Diana Ross and Berry Gordy, who is inducted as a nonperformer)
So if you want to get yourself into the Rock & Roll Hall of Fame, you might want to name that kid China, or some variation thereof. It's interesting to note that Chynna Phillips, who sang the soporific, ironically titled "Reckless" with Wilson Phillips, is the only one who's made music her career.
But really, I thought there would have been more. Some possible future additions to the list:
Chastity Bono (if Sonny and Cher get inducted)
Elijah Blue Allman (if Cher gets inducted)
Sally and Ben Taylor (if Carly Simon gets inducted, which she would be if I had anything to say about it, and, you know, I really ought to)
Jackson Smith (and at least one other whose name I couldn't find, but they'll count if the MC5 get inducted)
