[Tower Ravens] North West and Border Morris Sides - Help!

Hello all (this may be one for Katherine actually), I'm trying to organise some dance spots for my Histories of Morris conference in March. I want to book a GOOD North West side. I know Earlsdon, but are there any others more local to London? And if you happen to know of any local border morris sides that don't black up, then that would be great too(!!!) Any help would be much appreciated! Thanks in anticipation. Laura x
