Good to have a nice Welsh greeting Mags,"Diolch".! Yes very straightforward. 11a a little misleading Mondrian, in as much as there are actually FOUR letters in the clue..(6,8,3,9.)That includes 16a. Need help with the short 'uns (always the case.!) 59a & 55d...otherwise done & dusted.! Havehad a surfeit of R.T's recently...THREE in one week..! R:>
