Honestly no.  Though I think I managed to find a quick solution for now
using a temporary table.    This cuts down massively on the rows and
makes things pretty quick and slick overall.

I will however look at it, as it might explain why I was having
troubles.   If the join could have taken place after rows were cut down,
things would have been more efficient!

Thanks!
