I'm a little stuck... Click here to teach me more about this clue!

'source of disturbance in victoria station bar?' is the definition.
I can't tell whether this definition defines the answer.

'adapt to worcester mp a' is the wordplay.
'adapt' is an anagram indicator (I've seen 'adapting' mean this).
'to'+'worcester'+'mp'+'a'='toworcestermpa'
'toworcestermpa' anagrammed gives 'TWO-POT SCREAMER'.
