August 2019 Cryptic Solution

The solution to my August crossword is in an image behind this link.

Three answers were nods to specific people (*waves*). 5 was quite horrible to clue, but I liked where I got to in the end. 21 has a bit of dated knowledge required, maybe not one for the young’uns, but I didn’t want to go with the more obvious reference. 18 was my favourite. Right, toodle-oo!

Edit: Oh, I’ve just noticed that there’s a Nina down there. Entirely unintentional, but perhaps it was a subconscious tribute to Rutger Hauer. (It’s not easy being a dolphin.) And well done if you get any of those references.

Edit 2: Oh blimey, there’s another one! Well, just about. How bizarre.
