Like some old stage door Johnnies (4)

Ross

I believe the answer is:

aged

I'm a little stuck... Click here to teach me more about this clue!

'like some old' is the definition.
'aged' can be an answer for 'old' (I've seen this before). I am not sure about the 'like some' bit.

'stage door johnnies' is the wordplay.
'AGED' is hidden in amongst the letters.
But, I'm unsure how this is indicated.

Can you help me to learn more?

(Other definitions for aged that I've seen before include "Like Uncle Arly" , "well over the hill" , "not like a callow youth" , "Senior" , "Time-worn" .)

I've seen this clue in the Evening Standard.
