session musician advice needed

[paddy64]

Hi
I wonder if any of you use session musicians and if so what contract terms do you offer? Is there some standard legal contract out there that I can download- I know there are a few out on google, but are there any you would recommend as legally binding? I'm looking at paying a flat fee (no royalty).

I usually only use people I know, but I've got a couple of production music projects coming up where I'll probably need new people (particularly session singers) and I want things watertight from the start.
Thanks for any help
