'one too many' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'review the score draw' is the wordplay.
'review' is an anagram indicator.
'the'+'score'+'draw'='thescoredraw'
'thescoredraw' with letters rearranged gives 'THREES A CROWD'.

'there is' acts as a link.
