Dance a lot when tipsy, according to accounts (9)
I believe the answer is:
Here is my best explanation:
'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).
'dancealot' anagrammed gives 'ANECDOTAL'.
(Other definitions for anecdotal that I've seen before include "Unreliable or hearsay (account)", "Going by hearsay", "garrulous", "Like slightly unreliable report or hearsay", "as regards the story", "Like some amusing stories", "based on hearsay", "seen to be unreliable in court?", "Storytelling" and "Like a story".)
