Gluing Warped Plywood?

[javeryh]

I have had a few pieces of plywood cut for a CP for well over a year but I never glued them up.  When I initially cut them I did a dry fit and everything was nice and snug.  Fast-forward to today and the pieces have warped a little over time.  When I do a dry fit everything is still nice and snug but I have to really apply pressure to the clamps to get it to work.  Assuming I glue it up, will it hold over time?  Anyone have any experience with this? 

I could re-do everything but the cuts were very intricate (everything is mitred) and I also don't have any more scrap (furniture grade birch) plywood laying around.

i've seen people put warped plywood sheets under weights to straighten it out and that seemed to work OK after some time. Once its glued and screwed it usually holds ok as long as it is solid from the get-go from my experience...
