Cryptic crossword No 3,521

Thanks Primus for an enjoyable and timely tribute, albeit not one I had much previous connection with. Faves included 7a, 12a, 21a, 1d, 8d and 10d, which I do have some connection with and admire for its audacity! Cheers!

Thanks Primus. I decided to give this a go after seeing the SI. I enjoyed the puzzle but I found it tough in spots. Revealing the unfamiliar 10d and 4d helped me to the finish line. Favourites included 8a, 21a, 23a, 1d, and 14d. More in reply

Thanks for a fun workout! I especially liked 7a, 8a, 14a, 15a, 19a, 1d, 4d, 8d and 16d.
