Well, this one proved a real challenge for me. FOI 13 and then like others 24 and 20 got me moving forward. I struggled with the themed clues and the circular references until I hit upon 26. Slow progress after that with a couple of the 'loose homophones' holding me up.
Surprise, surprise I like Ianwil and Rocky7 initially went off track with 3.
I also spent too long parsing 18 despite being familiar with the sporting reference. I came here with a completed grid but one or two entries that I still couldn't fully parse.
Thanks to all the previous posters, your hints and comments have helped put my mind at rest.
