I found this a bit harder than usual, but maybe I'm just getting dimmer!
There are two clues with the same ending but, personally, I prefer rhyming pairs that have different spellings but I appreciate that's not always possible within the limits of a crossword.
15a was a new expression to me but it's in the Free Online Dictionary and the meaning and wordplay is clear, so no complaints.
There's also a really long initial letters clue - is this a record?
It's nice to see "one who went at 15mph" get a mention at 1a even if it seems so dated nowadays!
COD - I do like 12a but I'm going to pick 22d "Somewhat saucy and kind of blue (4) (Much like myself 😉)
Thanks to Everyman for an enjoyable puzzle.
Stay safe:-)
