Cryptic II

Disturbs awful pest in America;
clumsy centipede, essentially confused
upsets open vessels,
caught in denial, unexpectedly.
Macerate new scones and jam
left on plate? You, say! Tidy up!
Nasty rows about gold bring misery,
interim alterations to railway stations
racing track circuits partly collapsed
amusing or ridiculous, stupid person.
Add a very quiet finale-
bank gives heartless response.
