Old actress grand in last hurrah (4,4)

I think it could be either:

Which length description are you looking for?:

4,4

swan song

'last hurrah' is the definition.
(I know that last hurrah can be written as swan song)

'old actress grand' is the wordplay.
'old actress' becomes 'swanson' (I've seen this before).
'grand' becomes 'g' (G is short for grand as in a thousand).
'swanson'+'g'='SWAN-SONG'

'in' acts as a link.

(Other definitions for swan song that I've seen before include "Last appearance" , "Final utterance" , "Final performance, to the tune of an aquatic bird" , "A dying performance" , "Last performance of a career" .)

I've seen this clue in The Sun.
