I'm late to this but could someone cast their mind back please? I have finished but not happy with 21ac and 3dn. Isle and juror. Don't get the definition for first and can't see the connection between the two clues as suggested by the clue for the second.
Thanks Malone, forgot about key being an island but as you say it's Jura and the clue doesn't seem to suggest 'sounds like' unless 'on the radio' is doing double duty and anyway Jura doesn't sound like juro. Apologies for the grump.
TL: I think we all agreed here last week that this was a poor clue (tho' I suppose the -or is supposed to resemble the -a the way some people speak???..)
