Thanks shboa, I too love working with accompaniment when I get the chance. In the music school I'm lucky that my piano teacher usually does the accompaniments and Korrepetition (does that word work in English?) leading up to concerts and he's wonderful. But the poor guy is so exhausted by the end of the summer term he really needs a complete break and usually escapes to a silent Swiss mountain or somewhere!
It seems they've probably found a new teacher for next term, who comes from the same conservatory as my previous two, so fingers crossed. They've been great, good performers and well trained in the pedagogy side. I'll start work slowly on a couple from my new stock of repertoire and hopefully hold onto all I was taught by M.
Good luck with your new teacher.
