Late checking in as I only managed to get my copy this lunchtime. Thanks for the hints re 18a, as that was causing me problems. Although I have an answer which fits for 19d (although the clue reads 18d) I can't quite see the parsing. (I have a word ending in K) Maybe some lunch will help.
Just finished this one as I've been away visiting my daughter and new baby (Emily) so didn't start it till late. Just to clarify 18a - the answer was a 50s hit for Little Richard and also a TV programme for Robbie Coltraine. RT 9 arrived yesterday so must start on that now.
