Finally finished on account of not being able to get 18d because I had a different word for ring also beginning with h for 24a. Shows you should always attempt to parse solutions.
LOI as a result was 22a, a name I wasn't aware of.
FOI thanks to Brendan was 12a and that got me well on the way to getting 26.
COD on a very good puzzle I think was 17,19 though I liked 16d too.
