Cryptic crossword No 2,598

Yet another theme I'm unfamiliar with (shockingly) but I enjoyed the clueing. Hard to pick favourites but these are neat: 7a,8a,15a,16a,25a and 1d (great image!), 4d,14d,20d

Nicely done, Heron. You are certainly managing to keep your device going consistently and some of the undefined solutions would have been tricky to define so it worked well. I did have my suspicions but the key entry turned out to be last one in. Likes inc 7a (once I'd worked out the parse), 16a, 22a, 1d, 3d, 4d and 14d. Thanks. PM
