I've gone for HAFIZ for 6 DOWN, but can you explain the FIZ part of the wordplay. Could it be FIT, meaning GO, and HAFIT being a possible alternative spelling? I'm faxing my entry within next hour or two, so urgent response appreciated..
Hafiz - a Muslim that has the entire Koran committed to memory - 'Ha' (Hoc anno - Latin "in this year") + 'fiz' - informal term for "go", as vivacity; elan; spirit, etc
