Looking for approval, show sequence of old (3,4)

I believe the answer is:

run past

'looking for approval show' is the definition.
(to run something past someone is get permission)

'sequence of old' is the wordplay.
'sequence' becomes 'run' (I've seen this before).
'of old' becomes 'past' (both can mean historical or long gone).
'run'+'past'='RUN PAST'

(Another definition for run past that I've seen is " get another view".)

I've seen this clue in The Times.
