Export of all Role Based Prices

I have a client who set up a bunch of Role Based pricing elements in error (setting them on Customer and Logged Out/Visitor instead of on a custom role) and wants them removed. Is there an easy to use method or query I can run to find the products that have Role Based Pricing set on them? I don’t need a quick way to remove them all, I can do that myself, but I do need a complete way to figure out which ones I have to correct.
