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

'to be old people' is the definition.
(people of the Median Empire)

'possibly deems' is the wordplay.
'possibly' indicates anagramming the letters.
'deems' anagrammed gives 'MEDES'.

'me and mr lynam' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

I've seen this clue in the Evening Standard.
