Thanks to Vlad, that was a lot of fun.
Have no problem with 1d at all.
I feel clues like 20a deserve more praise for the way they work real-life characters (past or present) into the wordplay, only for the solver to then realise they've been led a merry dance. By their very nature, though, they are more difficult to compose and, as a result, can often appear clunky, so hats off to Vlad for making the surface of this flow relatively smoothly
Hadn't heard of 25a but was able to correctly get it from the wordplay and crossers.
COD: the beautifully succinct 18d.
