It could be possible that she'd work with David again. Think about it. He is her husbands best buddy. How hard would it be to be sitting around the house bsing and all of a sudden thing "damn that would be awesome in a song". Then the songwriting fires begin to burn. eh- It could happen
Altho it would be awesome to throw Ben into the mix once again. It could happen if Amy could put aside their differences and create some awesome stuff. It has to be hard to see how successful Ben has been since he left the group. He's one hellova songwriter and producer.
But alas, I'll probably have grandkids before there is even thought of another album.
