Fired! Client wants ALL project related material

How embarassing and professionally degrading. For, what I am told are creative diffrences, I was fired by my client after they watched the first cut of a short 11 minute doc I was editing for them.

I was working as an "at will" contractor hired by a video producer to edit and shoot some footage. My rate was good (80.00 / hr) and it was understood I was to edit on my own gear at my home studio.

My client (or boss as he states it) tells me that he wants all the work product turned over to him by end of day Tuesday - which he says should include all raw footage on tape, edited footage on tape, any graphics I created, any sound effects and music tracks I used or intended to use - and the actual project files from Premiere Pro which is what I edit with.

That's quite a laundry list. Do I need to turn all of this over to him? Or is he just entitled to original tapes and the edited production. I purchased the royalty free music library for myself and many of the graphics and effects are pre-sets I created prior to this production.

His email to me is very specific: he wants everything associated with this production to be turned over so work can continue seamlessly with another editor.
