Thanks Jim and Tom. At least now I've got a direction to head in. I

I'll probably separate out each sub query and store the results in a
table (would a temp table be a good solution here?) before I pull
it all
together with the final query.
Yes, it would. It's also possible that you could structure the query
better, to reduce the amount of concurrent sorting/hashing going on.
