I decided to do this before having a rest but that may have been an error as I have a completed grid with a green tick but no idea about the theme!
I managed to get all the themed words from wordplay alone.
FOI was 17a but the first themed clue was 27d.
I got held up for a while by initially getting 14a wrong which messed up 16d.
If you do get stuck (like me!) there are a couple of hiddens in the acrosses and a long anagram in the downs.
I've made a list of all the theme words and my plan is to look at them tomorrow after I've had a good sleep - sort of creep on them 😂
Thanks to Picaroon for very challenging workout.
As Geeker says, I think this will be a lively thread and am looking forward to seeing how many others are as confused as me.
Don't forget, if you get stuck, you only have to ask for a hint - there are always people on here willing to help.
Stay safe:-)
