Here's something from her board:
"
last year on Nov. 15 at the Patti Smith show in hollywood i met PJ and asked her when she would be collaberating with John Parish again because they did such a great job the first time. she said, actually, that they were recording some stuff and would hopefully be out in 2006. so i heard it straight from the source."

Not the best source in the world, but...
