Dance a lot when tipsy, according to accounts (9)
I believe the answer is:
anecdotal
'according to accounts' is the definition.
'dance a lot when tipsy' is the wordplay.
'when tipsy' indicates an anagram (I've seen this in other clues).
'dance'+'a'+'lot'='dancealot'
'dancealot' anagrammed gives 'ANECDOTAL'.
(Other definitions for anecdotal that I've seen before include "Unreliable or hearsay (account)" , "garrulous" , "as regards the story" , "Like some amusing stories" , "Narrative" .)
