Losing hair, Uriah Heep's playing southern city of old (7)

I believe the answer is:

ephesus

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

'city of old' is the definition.
'ephesus' can be an answer for 'city' (I have seen 'ancient city' mean 'ephesus' so perhaps 'city' could also mean 'ephesus'). I am not sure about the 'of old' bit.

'losing hair uriah heep's playing southern' is the wordplay.
'losing' is a deletion indicator.
'playing' is an anagram indicator.
'southern' becomes 's' (abbreviation).
'uriah'+'heeps'='uriahheeps'
'uriahheeps' with 'hair' removed is 'uheeps'.
'uheeps' is an anagram of 'ephesu'.
'ephesu'+'s'='EPHESUS'

Can you help me to learn more?
